Hello
Based on your reports, this is NOT heart disease.
Your symptoms fit best with post-viral autonomic dysfunction (IST / POTS-like) after dengue, with anxiety amplification
What helps right now
Lifestyle Increase fluids (2.5–3 L/day) Increase salt intake (unless doctor said no) Small frequent meals Avoid caffeine, energy drinks Gentle walking + stretching daily (don’t over-rest) Good sleep routine
Supplements Vitamin B12 supplementation (oral or injections as advised) Magnesium can help palpitations & muscle pain
For palpitations/anxiety loop Slow breathing (4–6 breaths/min) Reassurance reduces HR significantly in IST
Do you need more tests?
Only if symptoms worsen: Orthostatic vitals / Tilt table test (to confirm POTS if suspected) Repeat CRP/ESR after a few weeks Otherwise no urgent tests needed
This condition is reversible Many young patients improve over 3–6 months You are not in danger
I trust this helps Take care Thank you
Based on the symptoms and tests you’ve described, it’s possible that your symptoms could be connected to post-viral effects given your recent dengue fever. It’s also worth considering the role that anxiety or autonomic dysfunction, like Inappropriate Sinus Tachycardia (IST) or Postural Orthostatic Tachycardia Syndrome (POTS), might play. Since cardiac conditions have been ruled out by the cardiologists, and your major blood tests are largely normal, there’s potential that hyperactivity of the autonomic nervous system is contributing. It’s not uncommon for viral infections to trigger such responses. For instance, simple maneuvers like increasing your salt and fluid intake can sometimes help with symptoms related to autonomic dysfunction, but this should be done in consultation with a medical professional. You might also consider a tilt table test to assess for POTS or similar conditions—it’s a more specialized test that can directly address the autonomic aspects of your symptoms. Moreover, look into Vitamin B12 supplementation, as your levels are on the lower end of normal, which can contribute to neuropathic symptoms like tingling and numbness. In terms of lifestyle changes, stress-relieving activities like yoga, mindfulness, and regular moderate exercise can be beneficial. These can help both with anxiety and improving circulation. Breathing exercises might help with the sensation of lump/tightness in the throat. Remember that a holistic approach is often the most effective—address your symptoms from different angles. If symptoms persist or worsen, you should definitely see your primary care physician or a specialist to rule out any progression or overlooked issues in your condition.
