Understanding Elevated Heart Rate and Difficulty Breathing: Insights Needed
I’m a 40-year-old Caucasian woman residing in the UK, standing at 168 cm tall and weighing 67 kg. I am definitely not expecting a child, am a non-smoker, consume alcohol only on rare occasions, and lead a moderately active lifestyle with regular cycling and walking. My current medications include Sertraline, which has recently been increased from 100 mg to 150 mg over the past month; I had been at the lower dose for six years. Additionally, I've started taking magnesium and vitamin D supplements. Regarding my health history, I've dealt with mild lower back pain for over seven years and suffer from significant anxiety and obsessive-compulsive disorder. Aside from these issues, I have no notable medical problems. On my father's side, there is a history of cancer, including prostate and breast cancers. I have tested negative for BRCA and related mutations, and last year I underwent my first mammogram as part of an early detection program due to my family history, which returned normal results. I believe I might be entering perimenopause as evidenced by some symptoms such as shorter menstrual cycles, itchy vulvar skin, and since my mother experienced menopause at 45, I suspect I may be having similar changes. Currently, I have been feeling a sensation of "air hunger," as if I'm unable to fully inhale, paired with an increased heart rate, resting around 80 beats per minute, over the last four days. Prior to this, I experienced mild discomfort in my upper back and shoulders along with tension headaches that have since subsided. Yesterday I sought treatment at the A&E due to my breathing difficulties and heart palpitations. My blood oxygen saturation was noted to be around 96-97%, and my blood pressure remained normal. Upon admission, my heart rate was initially 130 beats per minute, later dropping to 107. I underwent an EKG, which indicated a normal rhythm but was fast, and subsequent blood tests showed results mostly within acceptable ranges except for a low APTT and APTT ratio, and a slightly elevated MCHC. The D-dimer test returned negative, and I’ll provide a detailed account of my blood results in a comment shortly. No chest X-ray was performed; however, a physician assessed my breathing and back with a stethoscope, concluding that there were no abnormal sounds detected. The normal blood test results suggest that anemia, which could explain my symptoms, is not an issue. I do recognize that anxiety and panic can present with similar symptoms, but this current episode feels different to me, lasting longer than typical and lacking a clear emotional or psychological trigger. I am particularly worried about the implications of having a low APTT, which I understand can point to bleeding disorders or malignancies. Other conditions influencing APTT don't seem relevant to my situation as far as I'm aware. I also fear the possibility of a pleural effusion potentially linked to some form of cancer due to my symptoms of breathing difficulties and elevated heart rate. Notably, I do not have a cough or experience hemoptysis, nor do I have any chest pain, although I occasionally sense a mild pressure or tightness in the area. Would it be prudent for me to pursue specific follow-up actions? Is it advisable to wait and see if my breathing and heart rate issues improve on their own?

Your experience of elevated heart rate and breathing difficulties can understandably cause concern, especially given your health history and recent changes. It’s reassuring that your tests have mostly shown normal results, and while low APTT can raise questions, there are many potential causes that might not relate to serious conditions.
Key Points
- Understanding Symptoms: Your feelings of "air hunger" and elevated heart rate can be linked to anxiety, hormonal changes, or even physical tension in your back and shoulders.
- Monitoring the Situation: Given that you recently had an evaluation that ruled out many serious conditions, observing your symptoms while adopting some self-care strategies might be a reasonable next step.
Explanation
- Normal Test Results: Your blood oxygen saturation and other tests showing mostly normal results offer some reassurance. Low APTT can be due to various factors, such as hydration levels or how your body processes certain medications, and it does not automatically indicate a serious issue.
- Connection to Anxiety: Symptoms like difficulty breathing and heart palpitations can indeed stem from anxiety or panic attacks, which may manifest differently at times and can vary in duration.
- Hormonal Changes: As you mentioned possible perimenopausal symptoms, hormonal fluctuations can also influence heart rate and breathing patterns.
Next Steps
-
Monitor Symptoms: Keep a detailed diary of your daily symptoms, noting when they occur, their intensity, and any patterns you observe. Look for potential triggers or improvements in your state throughout the week.
-
Self-Care Strategies:
- Relaxation Techniques: Practice deep breathing exercises, mindfulness, or meditation to help manage anxiety and promote relaxation. These methods can help ease your "air hunger."
- Physical Activity: Continue your activities like cycling and walking, which are great for overall health, but listen to your body. If you're feeling off, moderate the intensity and duration of your workouts.
-
Follow-Up Care: If your symptoms persist, worsen, or if you experience any new concerning symptoms (like significant chest pain or changes in consciousness), consider reaching out to your healthcare provider. They may recommend further evaluation or monitoring of your blood tests, particularly regarding your APTT levels.
While it may feel alarming to experience these symptoms, it is often helpful to focus on proactive and positive self-care. Remember to reach out for support from friends, family, or mental health professionals if you're feeling overwhelmed. You're not alone in this, and your health journey is worth monitoring carefully.

Painful Knuckle After Injury: Is It Arthritis or Something Else?
I'm a 37-year-old male, standing at 6'1" and weighing 170 pounds. I've been experiencing discomfort in the knuckle of my middle finger for the past four months. I have no prior medical conditions, don't take any medications, and I neither smoke nor drink, living in the USA. Several months back, during a move, I overexerted myself while carrying a large number of boxes, which resulted in injury to multiple fingers on my left hand, particularly affecting my middle finger. Initially, I didn’t notice any problem until a few weeks later when I felt a sharp pain while moving my fingers across a surface. Recently, while I’ve noticed some signs of improvement – I can now move my fingers without significant discomfort – the pain in my middle finger persists, especially when I attempt to crack the knuckle. This motion causes a sharp pain that lingers for about a minute. Observing the knuckle reveals a noticeable bulge on the right side, which wasn’t present before. Additionally, my other fingers are also experiencing some pain, which reinforces my belief that this is related to my moving activities. However, I am increasingly anxious about the possibility of developing arthritis in my middle finger. Despite the ongoing pain, I can still move my finger freely; there’s no limitation in mobility, and rubbing the knuckle doesn’t elicit pain – it’s just the cracking motion that causes discomfort along with the unusual bulge. I plan to consult with a physician about these concerns. Could this be arthritis, or is it more likely a tendon or ligament issue stemming from my recent move? Can such ligament or tendon issues lead to pain during knuckle cracking or cause swelling? This situation has definitely caused me more stress than it should have.
Persistent Muscle Pain for Months – Seeking Insights
Greetings, I find myself in a challenging situation and need to share my experiences. After consulting numerous healthcare professionals, I've yet to uncover the cause of my ongoing anguish. I'm enduring significant pain and am eager for any guidance or explanations that could shed light on my condition. I am a 27-year-old female, standing at 5 feet 6 inches and weighing around 220 pounds. I vape every day and consume alcohol about once a month, while I do not use marijuana. For the past seven months, I have been grappling with debilitating pain throughout my body. Official Diagnoses: Polycystic Ovary Syndrome (PCOS), Hypermobility, Pilonidal disease (experienced three flare-ups this year). For the last seven months, it feels as though my body is waging war against itself. My ordeal began with intense pain in my left foot and calf—a sharp nerve sensation that prompted a visit to a podiatrist. Despite being diagnosed with peroneal tendonitis, imaging tests such as MRIs and X-rays did not confirm this diagnosis, leaving me puzzled. The pain was so acute that I developed a noticeable limp. I underwent physical therapy from August to November, but unfortunately, I saw no improvement. Doctors avoided steroid injections due to a potential risk of tendon rupture. I explored various footwear options, including Hokas and Brooks, which alleviated the discomfort somewhat, though it remains significant. At this juncture, I would rate the pain in my foot at a 4-5 out of 10, and I have recently started shockwave therapy. In August, I began to experience severe pain in the thoracic area of my back. I initiated physical therapy for this issue in October, yet the agony continues. Any twisting motion or walking beyond 2,000–3,000 steps provokes a flare-up, while staying under 2,000 steps keeps the pain around 6 out of 10. On November 17th, I received six cortisone injections in my back, which brought the pain down from 7 to 5.5 on average. Mornings are particularly difficult; movement helps to reduce the discomfort but physical therapy appears to neither improve nor worsen the situation. An MRI has been conducted, and I will review the results next week, but I expect them to be normal. Recently, over the past two weeks, I have been experiencing excruciating pain in my shoulder and neck region, particularly the trapezius muscle. The pain is sharp, making it nearly impossible for me to utilize my left arm for daily tasks; I even struggled to brush my hair this morning and experienced multiple disruptions to my sleep due to discomfort. Current Pain Levels: - Foot: 5/10 - Back: 6/10 - Shoulder/Neck: 8/10 Additional important observations: Upon taking ibuprofen, I notice significant relief; my foot pain diminishes to 1/10, back pain reduces to 3/10, and shoulder pain falls to 5/10. I am contemplating the possibility of Mast Cell Activation Syndrome (MCAS) because I have noticed that my skin turns red and becomes inflamed upon contact, plus I have dealt with chronic hives for my entire life. I tested positive for HLA-B27, yet X-rays do not indicate the presence of Ankylosing Spondylitis. I have been diagnosed with hypermobility but did not fulfill the criteria for Hypermobile Ehlers-Danlos syndrome. Tests for lupus returned negative results, and ANA tests were also negative. My CRP is at 19, ESR at 22, while all other levels (WBC, RBC, liver function, etc.) remain within normal ranges. What could possibly be happening? My foot experiences a temporary reprieve one day, only for my back to flare up, and then as my back starts to improve, my neck begins to ache. I have drastically limited my walking to 2,000–3,000 steps daily, as I have found this volume is manageable. I’m investing in optimal sleep positions and trying various pillows (including lumbar and leg supports), but none seem to provide relief. Typically, physical therapy works for me, as I have a history of muscle strains. I apologize for the length of this message, but any assistance or insights would mean a great deal to me.
Sudden Sharp Pain in Achilles Tendon
I realize this topic has been discussed previously, but I haven’t come across a post that matches my specific experience, so I’m reaching out for some guidance: A little background: I’m quite a novice when it comes to running, but I’m gradually increasing my efforts. Just yesterday, I completed what felt like my toughest run to date, though it might still register as easy for seasoned runners. Here’s my setup: - 6-minute warm-up - 6 minutes of running followed by 1 minute of walking, repeated 5 times - 6 minutes to cool down - Additional stretching exercises Moments ago, I experienced a sharp pain in my Achilles—around a 7 out of 10 on the pain scale—that lasted for roughly 10 seconds before fading back to normal, leaving it feeling slightly chilly afterward. I didn’t hear any popping sounds. At the time, I was seated at my desk. This isn’t the first instance; I’ve had similar occurrences several times since I embarked on my running journey two years ago. In the past, I’ve taken breaks from running due to various life circumstances, and each time, the discomfort resolved itself. Now, I have a few questions: Why are these fundamental runs triggering this kind of pain? What measures can I take to alleviate it? Should I consider halting my running and starting from square one? (The thought of that is disheartening for me.) A bit about me: I’m a 35-year-old male, standing at 6'2" and weighing 180 pounds. I run 2 to 3 times a week and stretch nearly every day. Thanks for any help you can provide! :)
Navigating the Pain: Investigation for a 68-Year-Old Man's Hip and Thigh Discomfort
To set the stage for this case, it’s important to clarify that I'm sharing information about a family member rather than discussing my own health. The details provided are based on recollections and conversations, so the timeline may not be completely precise due to the nature of memory. I also want to acknowledge that my background is not in the medical field, and English is not my primary language. Therefore, please overlook any potential misinterpretations in terminology. I'm here to elaborate and answer any questions to the extent of my understanding. Here’s a summary of the relevant information: - **Patient Profile**: A 68-year-old male, measuring 184 cm (6 feet) in height and weighing 80 kg (175 lbs). He is of slim build with low muscle tone. - **Medical Background**: The only ongoing medication is for hypertension, which he has been on for approximately 15 years. This individual has a history of symptoms that may point towards issues such as esophageal stenosis or an unidentified dysfunction of the lower esophageal sphincter (LES). He frequently experiences food becoming lodged in his esophagus, inducing nausea. Occasionally, medical intervention has been necessary, such as the use of a gastroscope to alleviate these blockages. This has been a longstanding issue that appears to be worsening; however, it's unclear whether he has had a formal diagnosis, but it raises concerns about possible neuropathic conditions. **Surgical History**: Ten years ago, he underwent hip replacement surgery due to degenerative changes in the joint. There have been no discoveries of rheumatological conditions, with conditions related to the surgery noted as ruled out, although there may be some rare issue at play. **Timeline of Symptoms**: 1. **8-5 Years Ago**: He experienced intermittent pain in the hip and buttocks following the hip replacement, potentially exacerbated by inadequate physiotherapy and rehabilitation. 2. **7-5 Years Ago**: He started to notice that his bladder was not emptying completely, along with a heightened urgency to urinate, particularly at night. At this point, a diagnosis of benign prostatic enlargement was made. 3. **5 Years Ago**: Occasional muscle cramps and spasms developed in various muscles, including those in the feet and fingers, accompanied by some pain. This could be linked to electrolyte loss from the diuretic effect of his blood pressure medication. 4. **5 Years Ago**: He also experienced myokymia in larger muscle groups, such as the thighs, without any associated pain. 5. **2 Years Ago**: Severe swelling occurred in one leg, particularly around the ankle and calf, with some pain involved. No blood clots were detected, and the origin remains unclear. This coincided with a hot summer, possibly indicating an electrolyte imbalance. 6. **1 Year Ago to Present**: There has been an increase in pain and weakness in the hip and buttock area, radiating down the thighs. This discomfort has intensified recently, making it difficult for him to rise from a seated position without external support. His mobility has deteriorated to the point where he may need a walker, although he remains resistant to using one. 7. **1-2 Years Ago to Present**: There has been a reduction in blood pressure without any lifestyle alterations. He remains on blood pressure medication, but the dosage has been reduced by half. It's uncertain whether this is a symptom or simply a result of aging and a decline in vascular health. A few weeks ago, he underwent basic blood tests, which revealed results mostly within normal ranges, although some were borderline, such as elevated ALAT levels. He has a heavy alcohol consumption habit and maintains a somewhat restricted diet, which may lack variety, resulting in small portion sizes. He also tends to limit his fluid intake as he avoids nighttime bathroom trips. This combination of factors raises concerns about a possible electrolyte imbalance, although the symptoms seem too severe for that alone. Personality-wise, he is quite headstrong, which may be a factor but isn't likely a neurological issue. If anyone has insights or suggestions regarding the nature of his symptoms, it would be greatly appreciated. Could it signal a muscular, mechanical, vascular issue, or perhaps a deficiency? While I prefer not to contemplate serious conditions like MS or ALS, I’m open to any professional opinions based on the described symptoms. Finally, I'm eager to hear recommendations for tests, blood work, or imaging studies that could be useful in beginning to unravel this complex situation.
Seeking an MRI for Persistent Shoulder Pain?
A 24-year-old woman diagnosed with von Willebrand Disease (VWD) and Celiac Disease maintains an exceptionally clean diet, focusing on whole, organic foods. She has no history of heavy lifting or traumatic events such as car accidents. For over five years, she has experienced shoulder discomfort, undergoing extensive evaluations including blood tests, X-rays, physical therapy, and consultations with a psychiatrist, all of whom have remarked, "This is an interesting case," yet none have been able to determine the cause of her pain. Despite her persistent requests for an MRI, healthcare providers prefer to exhaust all possible options beforehand. Initially, the pain was mild, but it has progressively intensified to the point where there are days when using her shoulder becomes extraordinarily challenging. On bad days, her pain reaches an intensity level of 8 out of 10, while on better days, it hovers around 3.5. Although a simple arm pop once alleviated her symptoms, she now endures a throbbing and stabbing sensation that radiates from her shoulder to her bicep, significantly impacting her ability to sleep and perform daily activities. In the past, she could achieve rapid relief by popping her shoulder, but that reprieve seems elusive as the years have passed. Despite trying both heat and cold therapy, she has found no improvement. She diligently stretches twice daily and avoids activities that could strain her shoulder. Initially, treatments like Lidocaine and tiger balm provided some comfort, but they have recently begun to irritate her shoulder instead, exacerbating the pain. Her hematology specialists do not believe that her VWD plays a role in her symptoms. Frustration mounts as she, along with multiple physicians, remains at a loss regarding the nature and source of her ongoing discomfort. The mystery of her shoulder pain only deepens, leaving her feeling bewildered and desperate for answers. 😓
