Unexplained Heart Symptoms: Seeking Answers

4/3/2025, 11:20:28 AMMale25-34

I am a 17-year-old female, standing at 5'3" and weighing 165 pounds, with a medical history that includes infective endocarditis, for which I am currently receiving tri-weekly penicillin injections. Additionally, I have minor leaks in both my tricuspid and mitral valves, alongside a trivial pulmonary leak. I also manage asthma along with anxiety and depression, currently treated with 20 mg of Prozac. Over the past couple of months, I've noticed several troubling changes in my body’s functioning. Symptoms like excessive sweating, a rapid heart rate even while at rest, dizziness, and shortness of breath have become increasingly common. Following a routine check-up, I ended up at the emergency room where my resting heart rate was recorded at 133 beats per minute. While there, the only treatment I received was IV fluids, which proved effective in slowing my heart rate and improving my condition temporarily. Tests, including those for dehydration, vitamin levels, heart abnormalities, as well as a chest X-ray and echocardiogram, returned normal results—all looked good, including thyroid function. I felt relieved to return home, but soon after, my symptoms reappeared. As weeks passed, my condition has worsened. Typically, I lead an active lifestyle: I play football, navigate my area using a scooter, and tackle various household tasks such as mowing lawns and lifting heavy items. However, I've developed a troubling intolerance for these activities, leading to weight gain as I struggle to exercise without experiencing shortness of breath, palpitations, and nausea that has forced me to take breaks from gym class. Dizziness has escalated to the point where I experience ringing in my ears every time I stand up, necessitating physical support to prevent falling; I feel as though I am on the brink of collapse nearly every day. This has been compounded by extreme fatigue, often sleeping more than 20 hours a day, missing school, and grappling with a pervasive sense of malaise. I have undergone ultrasounds of my abdomen, all of which yielded normal results. Blood tests indicate that my iron levels, liver function tests, kidney function, and cholesterol are all satisfactory. Despite consuming three full meals daily, my symptoms resemble those of hypoglycemia or the general sensation of being deprived of food, even though my HbA1c levels are well within normal limits. Could this all stem from anxiety, or might there be another underlying cause? I would greatly appreciate any insights regarding potential explanations for my symptoms, or if you think a revision of my anxiety medication is in order. I have a Holter monitor test scheduled in a few days and an appointment with my cardiologist shortly thereafter, so any advice would be immensely helpful. I apologize for the lengthy post, but I needed to share my experience.

You're experiencing a combination of concerning symptoms, including excessive sweating, a rapid heart rate, dizziness, and extreme fatigue, which can be distressing. Given your medical history of infective endocarditis and current valve leaks, it's important to address your symptoms carefully.

Main Observations:

  1. Symptoms and Context: Rapid heart rate (tachycardia), shortness of breath, dizziness, and significant fatigue could relate to several factors, including anxiety, medication effects, or cardiac issues.
  2. Normal Test Results: Your tests (echocardiogram, blood tests, etc.) indicate no acute heart problems, but symptoms persist, suggesting other causes may be involved.

Possible Explanations:

  • Anxiety: Anxiety can amplify physical symptoms, leading to elevated heart rates, sweating, and fatigue. Given that you are currently on Prozac, a change in your anxiety could influence how the medication is working.
  • Cardiac Symptoms: While your heart tests were normal, the combination of your history and current symptoms warrants close monitoring, as valve leaks can sometimes impact heart function over time, especially with increased physical activity.
  • Dehydration and Electrolyte Balance: Although tests showed normal electrolyte levels, it's possible fluctuations in hydration status or minor imbalances could cause some of your symptoms.
  • Fatigue and Sleep Patterns: Excessive fatigue and sleep disturbances might suggest other underlying issues, possibly related to your mental health or even dietary factors.

Next Steps:

  1. Holter Monitor Test: This will provide valuable information on your heart's activity over time, especially during periods of symptoms. It's crucial for understanding any abnormal rhythms or patterns.

  2. Communicate with your Cardiologist: Share all your symptoms in detail, especially noting how they've impacted your daily life. Discuss the results of the Holter monitor thoroughly.

  3. Monitoring Anxiety: Since your anxiety could be contributing to your symptoms, consider discussing your current medication with your healthcare provider to explore whether an adjustment or an addition of another treatment modality (such as therapy) might help.

  4. Physical Activity and Gradual Return to Exercise: Gradually reintroducing physical activity may be beneficial; start with low-impact activities when you feel able. Consider also techniques for managing breathlessness and palpitations, like paced breathing exercises.

  5. Maintain a Symptoms Journal: Track when your symptoms occur and their severity. This can help identify potential triggers related to activities, food intake, or stress levels.

  6. Stay Hydrated and Mind Your Diet: Ensure you are drinking enough fluids throughout the day. Keep an eye on your diet to maintain balanced blood sugar levels, incorporating regular meals to avoid feelings of hypoglycemia.

Conclusion

I understand this is a lot to manage, but taking these actionable steps can help clarify your situation and support your overall health. Be sure to lean on your medical team for support, and don't hesitate to reach out for help when needed. Your health matters, and it’s important to prioritize both physical and mental well-being.

Significant Increase in Blood Pressure Over Two Months

Two months ago, on December 10th, 2025, I visited a CVS minute clinic due to a sinus infection, where my blood pressure was recorded at 120/74. However, during a recent visit to my general practitioner for my yearly health examination, my blood pressure soared to an alarming 200/114. The staff measured it multiple times, suspecting an error, even using a different device. The lowest reading captured was still quite high at 191/118. After discussing my situation, the doctor inquired whether I had a blood pressure monitor at home, which I do, and advised me to monitor my readings closely. Currently, after taking multiple readings, the most favorable result was 202/114, which is causing me some concern. - Female, age 39 - Weight: 175 lbs, Height: 5'2" - Non-smoker - Social drinker - No specific dietary restrictions - Sedentary lifestyle - No known family history of heart disease - Currently taking 20mg/day of Escitalopram and 450mg/day of Bupropion for anxiety and depression Online resources suggest that my readings indicate a "hypertensive crisis," a term that sounds rather serious. Despite my weight issues, these figures appear excessively high. I plan to message my GP for a follow-up, but I am wondering how alarmed I should be in the meantime?

Advice Needed on Possible Heart Condition (ASD)

Greetings everyone, I am a 27-year-old individual. Towards the end of 2022, a preliminary 2D echocardiogram raised concerns regarding a potential Atrial Septal Defect (ASD). Consequently, I underwent several follow-up echocardiograms and treadmill tests throughout 2023 and 2024. Fortunately, all results returned to be normal, and subsequent assessments indicated no structural issues with my heart. I also had a thorough evaluation at Apollo Hospital, which yielded normal findings as well. Later, during a consultation at Manipal Hospital, I was informed that the symptoms I am experiencing might be linked to anxiety or excessive worrying. Additionally, my lab tests revealed elevated levels of cholesterol and blood sugar, which fall into the prediabetic category. Currently, I do not experience chest pain, but I Continue to suffer from palpitations and a fast heartbeat, particularly when engaging in physical activities like climbing stairs. Despite receiving normal cardiac evaluations, these troubling symptoms persist, leading me to wonder if ASD has truly been dismissed or if I should consider further testing. I would appreciate any guidance on this matter.

Should I Request a Heart Evaluation from My Doctor?

**Personal Details**: 24 years old, no medications or substances, no existing health diagnoses, non-smoker, non-drinker, maintaining a healthy weight and height, engaging in regular physical activity. **Context**: During my time at university, I resolved to overcome my previous disinterest in academics and poor performance in school by adopting a comprehensive approach. This included selecting a challenging major, crafting a plan to finish my degree two years ahead of schedule, aiming for nothing less than As on exams, and ensuring my relationships with family and friends remained intact. However, my dedication to this plan resulted in significant stress. As I invested more time and energy into my studies, my anxiety about potential failure, looming deadlines, chaotic group projects, and unrelated personal issues escalated. Ultimately, this manifested as complications with my heart and blood pressure. What is most alarming is how I became accustomed to these health changes and dismissed the warning signs. I neglected to seek help from doctors or consider treatment options, essentially ignoring the symptoms entirely. **Health Issues Faced**: 1. **Heightened Sensitivity to Adrenaline**: Simply walking outside among people and traffic triggered noticeable spikes in my blood pressure. Roughly every thirty seconds, I experienced tingling in my abdomen, followed by a surge of pressure in my neck and a momentary slowing of my heart to manage the influx of blood pressure. Over the course of an hour, these occurrences added up, leading to possibly hundreds of episodes over days and months—quite concerning. 2. **Palpitations**: While this was not a constant occurrence, when it did manifest, it lasted for one to two weeks at a time. I would feel my heart racing, even during moments of rest at home. This would happen several times a day, persistently from morning until night. 3. **Elevated Heart Rate**: This was a continuous issue; my resting heart rate frequently soared into the 90s, even while sitting quietly. It often felt as though I was exerting effort, akin to physical activity, though I remained still. 4. **Chronic Tension and Sleep Disruption**: I dealt with ongoing feelings of tightness and inadequate sleep, at times leading to strange waking perceptions, such as seeing geometric shapes on surfaces upon waking. While not directly related to the previous issues, this level of sleep deprivation is undoubtedly harmful to one's health. These issues persisted for approximately two and a half years, but I have since regained my health. Nonetheless, I can't shake the feeling that I may have compromised my cardiovascular health due to these symptoms, which is why I am contemplating a heart evaluation with my doctor. I sought the opinion of an AI, which seemed dismissive, suggesting that given my situation and assuming no hidden health conditions, long-term damage was unlikely—perhaps even impossible. However, I would rather hear insights from healthcare professionals, so I'm reaching out for advice. Please share your thoughts!

Concerns About Ear Irrigation at the Pediatrician's Office for My Son

Summary: Can using a spray-type irrigation for ear wax removal harm a five-year-old? My child had a extreme reaction and experienced significant pain during and shortly after the procedure. I have a five-year-old son who suffers from severe allergies to both foods and environmental factors, alongside eczema which is mostly controlled. He takes Famotidine to manage reflux and a daily children's multivitamin, but does not regularly take any other medications. He has no history of surgeries. Although he has consulted with an ENT in the past, I don’t believe this is particularly relevant to the current situation, yet I will provide details later. During a recent well-visit at the pediatrician's office for five-year-olds, my son struggled with the hearing test, which marked the first time he did not perform well. In this examination, he wore headphones that emitted various beeps and was supposed to indicate which ear he heard the sounds from. The staff expressed concerns regarding his performance on the left side. As our assigned provider, the Physician's Assistant (PA) examined his ear and noted the presence of wax, suspecting it might be impeding his hearing. When she attempted to use a plastic curette, my son resisted and stated that it hurt. The PA remarked that the wax was harder than she anticipated, leading her to opt for an irrigation method to remove it. The nurses proceeded to administer some red-tinted drops, which he tolerated other than their cold temperature. A few minutes later, he laid down, and they used a spray bottle to irrigate his ear. At this point, he screamed as though we had never experienced before—he fought against the staff and cried intensely, even holding his breath to the extent that they needed to remind him to breathe. His reaction was reminiscent of when he has sustained a severe injury, such as from a significant fall. His cries of pain made it clear that he was genuinely suffering. After only a few moments, they decided to halt the procedure, presumably realizing that his discomfort was not an act of dramatization, and I was on the verge of stopping them myself due to my rising concern. When he eventually settled down, I inquired about the nature of his pain: whether it was a hot or burning sensation, a sting from the cold water, or a feeling of pressure in his ear. He communicated that it felt like it was going to burst inside, which suggests pressure-related pain. The irrigation attempt did not fully clear the wax they noticed. Now they are recommending that we use Debrox drops daily combined with a warm washcloth pressed against his ear after a steamy bath each night. We are to return in two weeks to check if the wax has been successfully removed and to retest his hearing. Though he appears to be okay now, he is visibly upset due to the discomfort from the procedure, especially since he had begged them to stop. He has also mentioned a sensation of water still being trapped in his ear and has been tilting his head intermittently as if it bothers him. This all transpired today right after the irrigation session. Could the forceful spraying of water have caused any damage to his eardrum, especially considering the intensity of his screams? I have previously experienced a perforated eardrum and am anxious about the potential harm this procedure may have inflicted on him. We avoid using Q-tips and inserting anything into his ears. What preventive measures should we adopt routinely to avoid wax buildup? This marks the second instance of noticeable wax at his pediatric visits, despite him bathing daily. I am puzzled as to why only one side is accumulating wax. Last year, the first attempt at wax removal was successful using a curette. ENT Background: At age three, my son was having trouble sleeping. An ENT suggested a tonsillectomy and adenoidectomy, although there were no other alarming symptoms to justify the surgery besides his restlessness at night. We sought a second opinion, where the new ENT indicated that while his tonsils appeared fine, his adenoids were mildly enlarged and might be beneficial to remove. However, due to COVID-19 and RSV, the surgery was postponed twice, leading us to reconsider the necessity of the operation. Given that he is now sleeping better, we have yet to pursue surgery thus far. I appreciate you taking the time to read through this lengthy account!

Experiencing Heart Pounding After Stopping Sudafed: Is It Cause for Concern?

At 24 years old, I've been experiencing a sensation that my heart is racing as if it's about to burst. This all started after I was dealing with a severe sinus infection and decided to take Sudafed extended-release tablets for six consecutive days. Ever since I discontinued the medication, my heart feels as though it's beating excessively hard, reminiscent of a fight-or-flight response. Should I be alarmed by this change, or could it possibly be a side effect from the Sudafed I had been using?
