Hi, Welcome to Healthcare Magic Forum.
You haven't mentioned your age and gender? Since you've said, you have this pain since 4 to 5 years, if you have no other problem other than this, it may be related to anxiety
. Are you Diabetic or Hypertensive? Does the pain increase when you walk or do uphill task? If yes, get a ECG done immediately. Get a Physician evaluation as soon as possible and if you are overweight
reduce your weight by regular exercises. In the meantime, reduce stress
and sleep for a minimum of 8 hours daily. Take Tab. Pantocid
40mg once daily on empty stomach half hour before breakfast for 2 weeks.
