Hi. I am 26 year old male. And since 5-6 days I am having a vibration like effect in my upper left chest area. It occurs on random timings and lasts for sometime or even couple of hours. First I thought this is due to acidity but isn’t. I also have minor cough. Current heart rate – 76-80 BPM I want to know due to what this is occurring and the solution to this. I am quite worried about it. And also this is not gastritis.
