Experiencing Numbness in Left Knee

7/3/2025, 4:20:26 PMMale25-34

I’m a 19-year-old female, standing at 5 feet 5 inches and weighing 127 pounds. I have hypermobile Ehlers-Danlos syndrome, postural orthostatic tachycardia syndrome, and Raynaud's phenomenon. My current medications include Adderall, Wellbutrin, Motegrity, Vitamin D, Vitamin C, and magnesium oxide. Recently, I encountered a concerning issue with my left knee. It was yesterday when I awoke to a distinct numbness in the area. While I still retain movement in my knee and am able to feel pressure when I scratch, lighter touches result in no sensation. There’s no tingling or pins and needles associated with it; rather, it resembles how my hand felt last year after receiving a numbing injection for stitches—present but devoid of feeling. This numbness has persisted for more than 24 hours and shows no signs of improvement. It affects a region extending an inch or two above and below my kneecap, primarily on the front and sides; interestingly, the back remains unaffected. The entire kneecap is involved, with the inner right side being the most numb segment. When I sit or apply pressure, the lack of sensation is pronounced. While there is no pain, the experience is undeniably strange. I had considered simply waiting for the numbness to subside since my legs tend to fall asleep from unusual sitting positions, but this is noticeably different. As an athlete, I am cautious and don't want to overlook something that could potentially be serious. Would it be wise to keep monitoring this situation, or is it advisable to consult my healthcare provider?

Experiencing numbness in your knee can raise valid concerns, especially given your existing health conditions. While numbness can sometimes result from temporary factors like compression or positioning, your specific situation warrants careful attention, particularly since the numbness has persisted for over 24 hours and is affecting your ability to function as an athlete.

Explanation

Numbness around the knee can stem from various causes including nerve compression, circulatory issues, or even changes related to hypermobile Ehlers-Danlos syndrome (hEDS). Given the uniqueness of this sensation and its localization, it's essential to consider how factors from your existing conditions may overlap with new symptoms. It's good that you're proactive, as it's crucial not to ignore unusual sensations.

Prioritized Next Steps:

  1. Monitor Symptoms: Keep an eye on any progression or changes in the numbness. Check if it spreads, increases, or if you gain any additional symptoms like weakness, changes in skin color, or swelling.

  2. Limit Stress on the Knee: Avoid activities that may exacerbate the numbness, such as intense workouts or prolonged sitting in positions that may compress the knee area.

  3. Gentle Mobility Exercises: If pain allows, incorporate gentle stretches or mobility exercises focusing on your knee and leg. This can help maintain blood flow without straining the area.

  4. Positioning: Be mindful of how you sit or sleep, ensuring you're not putting unnecessary pressure on your knee that could lead to numbness.

  5. Consult Your Healthcare Provider: Since this symptom differs from your usual experiences and has persisted, it's wise to reach out to your healthcare provider for further evaluation. They may want to assess for nerve involvement or other factors related to your other medical conditions.

Monitoring changes and maintaining mobility while seeking medical input is critical at this stage. If you notice any severe changes or new symptoms, don’t hesitate to seek immediate help.

Understanding CRP Levels: A Personal Concern

I am a 32-year-old female, weighing 123 lbs and standing at a height of 5’6". I'll keep this brief as I'm experiencing multiple symptoms that leave me feeling incredibly unwell. Over the past five years, my C-reactive protein (CRP) levels have been checked four times, consistently reflecting very low and healthy values, such as 0.04 and 0.1. Yesterday, I visited my physician to discuss my troubling symptoms, as I genuinely feel like my health is deteriorating. With a family history of autoimmune diseases and a positive ANA test result from 2014, I had previously failed to find clarity on my condition. However, my most recent CRP measurement is 4.6 mg/L, and my doctor deemed this level as "normal". This leaves me perplexed; how can this be considered normal given the extreme discomfort and sharp pain I’m experiencing? Additionally, my complete blood count (CBC) results indicate elevated levels of leukocytes, neutrophils, and white blood cells. I'm unsure if these findings are significant. Why is this CRP value regarded as normal for me when it has never reached such levels before, especially while I am feeling so miserable? The doctor also mentioned my vitamin D levels are low, but my result of 10 ng/ml seems quite concerningly deficient. Can anyone shed some light on this situation?

Seeking Guidance on Persistent Back Pain from Specialists

Hello, I’m a 23-year-old male experiencing a debilitating sharp pain in my upper back, peaking at around 7 on a scale of 10. This discomfort has persisted for two weeks without an identifiable cause or any recent injuries. Although I cannot specify the exact location, I believe it radiates from somewhere between the C7-T2 vertebrae and my right shoulder blade. The pain often manifests suddenly, particularly when I bend my upper back, raise my arms, take deep breaths, or perform any movement that utilizes the muscles connected to my spine in that region. Additionally, there is some radiating discomfort towards my right chest during inhalation, albeit less intense. Interestingly, I find relief when I slump in a static position, walk, lie down (especially), or engage in exercise – although the pain tends to worsen after physical activity. This issue seems to have begun following two weeks of extensive computer use, where I logged over eight hours daily. Initially, I experienced sharp shooting pains while bending my upper back for three days, after which this persistent pain developed on my right side. I have attended three sessions with a physical therapist, yet she was unable to identify the underlying problem. Now, I feel overwhelmed by the potential causes and uncertain whether I should prioritize rest or further physical activity. I’ve experimented with taking a day off and attempting the prescribed PT exercises, but I haven’t noticed any improvements; the situation remains unchanged. Given that healthcare professionals in my locality have not been helpful, I am inclined to conduct my own research and possibly consult an osteopath who has a proven track record. Where should I begin?

Pain in the Upper Central Abdomen

Age: 24 | Height: 5’8 | Weight: 125-130 lbs Hello everyone, I’m reaching out for some guidance. Currently, I’m living in England and have been experiencing persistent upper middle abdominal discomfort for the last two months. These episodes strike unexpectedly, typically at night, and can last for several hours. The intensity of the pain is such that I find no relief. I consulted with a NHS general practitioner here, expressing my concerns about the possibility of gallstones or an ulcer. However, she seemed to discount my worries, attributing my symptoms to my age and perceived health status, labeling me as “young, active, and slim.” I’m curious if anyone has insights into what might be causing this issue. Should I consider visiting a private healthcare provider here in England, or would it be advisable to return to the US for a consultation with my regular doctors? The GP diagnosed me with indigestion after I mentioned that over-the-counter medications like Pepcid and Tums did not alleviate my pain, leaving me unsure about my next steps.

Unexpected Ankle Swelling Without Injury

At 29 years old, I’m a woman diagnosed with EDS and CRPS in my right hand. I don't smoke and acknowledge that I am on the heavier side. Yesterday morning, I awoke to discover my ankles were unusually swollen on both sides. The discomfort is significant, making it difficult to sit or walk. I have attempted to alleviate the issue by elevating my feet, applying compression, and using ice, yet I remain quite anxious about the sudden onset of this problem. Today, I visited my doctor, who scheduled a physiotherapy appointment for the end of the month. I can’t help but feel that this is too long to wait for help. Although I’m contemplating a trip to the emergency department, I’m hesitant because I don’t wish to burden them unnecessarily. Interestingly, there is no warmth or discoloration present, but I do experience a sensation of weakness and a slight numbness. Occasionally, it feels as though there are mild tingling sensations alongside pins and needles—about a level 1 on a scale of 10 for discomfort. Any guidance or advice would be immensely appreciated, as I’m concerned this might evolve into another area affected by CRPS.

Concerns Surrounding Septal Perforation for a 25-Year-Old Woman

**25-Year-Old Female - 5’0, 165 lbs - Questioning Septal Perforation Concerns** I recognize that this topic has been explored by others previously, and while responses might seem straightforward, I’m seeking some clarity to help alleviate my ongoing health-related anxiety. Currently, I perform Neil-med sinus rinses three times a day, and I maintain nasal moisture with products like Aquaphor, coconut oil, and nasal gel. This routine isn’t intended as a permanent solution, and I do plan to reduce these practices eventually, but I'm not quite ready for that yet. **Background Information:** - For over a decade, I have battled sinus complications. - I was born with a deviated septum, which has become increasingly noticeable with age. - After a CT scan in September, I was diagnosed with sinusitis, showing mucosal thickening but an intact septum. - Pain began in September and was initially thought to be a severe sinus infection. - In December, a swab test was conducted for Staph during this ongoing issue. - A course of Doxy was prescribed in January but I found little benefit. - In May, I was given a 21-day prescription of Amoxicillin-Clav with minimal improvement. - A 10-day course of monofloxacin in June effectively cleared the infection. During my doctor visit in **May**, she noted that my nasal passages appeared normal, prescribing treatment for chronic sinusitis. In my **June** follow-up, she expressed concern after examining the left side and contacted an ENT on call, initially suspecting an abscess. However, the specialist indicated that it was likely a localized infection resulting from the deviated septum. The monofloxacin treatment was effective up to that point, though no remarks were made about the right side, which she said looked fine. After a follow-up in **July**, my doctor informed me that although the infection cleared, there was still a noticeable bulging due to persistent inflammation. She conveyed no worries regarding this issue. When examining the right side, however—the previously declared healthy side—she observed significant scarring on the septum, claiming it is severely deviated. Given my overwhelming health anxiety, I’ve invested a lot of time trying to pinpoint the original cause of my symptoms. Now, after finally feeling better, I fear the possibility of a perforation without any awareness of it. Nevertheless, the ENT does not seem alarmed, and I have a long wait for my appointment—around six months. I do not exhibit any signs typically associated with perforation, such as bleeding or excessive pain. I use nasal plugs, but beyond that, the discomfort has resolved, with no crusting or nosebleeds noted. Recently, I’ve merely observed a thin layer of white tissue or mucus on both sides since completing the monofloxacin treatment. Could this indicate healing processes or the presence of immune cells? To date, I haven't experienced any symptoms that suggest cartilage has been damaged or that I’m at risk of perforation. Although I have occasionally burst a blood vessel due to forceful blowing, those instances resolve quickly with no other alarming symptoms suggesting an impending issue. When I inspect my nasal passages, I don’t see a hole and no light penetrates through. There is an indentation on the right side, but given my significant septum deviation, could this be considered normal? **In summary**: Since my health has improved, I have noticed increased congestion, mucus, and additional sneezing, alongside that thin layer of white tissue. It looks almost like peeling skin, very bright white in color. **My inquiries are as follows:** - Has anyone experienced anything similar? - Am I safe, or is there something I should be cautious about? - Do my symptoms indicate that a perforation is forthcoming, or am I overanalyzing? - Could this white tissue be a sign of healing or an immune response? Is it concerning? - What should I expect to see if I had actual scar tissue within my nose? - Would I be experiencing pain if that were the case? I acknowledge that I'm in charge of my health decisions and I'm not aiming to downplay any risks; I merely seek to understand the reality of my situation. With my ENT appointment at least six months away, the uncertainty drives me to distraction. While the alleviation of my original symptoms fills me with hope, my doctor's comments have left me feeling anxious. Thank you for any advice or personal stories you can share; it truly helps ease my mind.
