Hello. My age is 37. I have been experiencing chest discomfort from last 3 days sometimes pain while doing any activity. I have taken ecg which came out normal and 10 days back i have taken ecg and doppler echo which were also normal. I took diclofenac tablet i felt better for few hours after 9 hours again i feel the discomfort. Could you please suggest. I have taken the stress test 1 year back which was also normal and troponin test was normal. I have been taking multiple ecgs over a period of time which was normal. This is impacting me psychologically. Please help. Thank you.
