Your age is important here which u have not mentioned.Chest pain

Non Cardiac chest pain reasons are
2.Pain due to gastritis
I think you might be suffering from one of the above mentioned causes after reading your complaints
Take Cap Pan D 40 mg 1-0-0 before breakfast for 15 days, Take Tab Equiflex 1-0-1 after food for 3 days.Avoid coffee/tea, spicy food, avoid lifting heavy weights.
See if your symptoms improve, if not you have to visit a local doctor for proper diagnosis of the cause of your chest pain.
