Constant chest pain (at the center) One?

I am suffering from chest pain since last 1 year but i ignore it because it doesn't feel me much pain but one day when i woke up i was unable to breath properly due to so much chest pain (cheat paim in center of the chest). so i consult doctor next day, he gave me some medicines and then dr. told me for CBC and ESR test and result of that test are ok. Dr. gave me some medicines and my pain stopped at that time but that pain rise again after 1 month, and again i consult dr. and he gave me again some medicines and my pain stopped at that time. but again my pain started. so i changed my dr. and second dr. gave me pinap-d3 tablet and told me for heart echo from apollo or escort (strictly told for that hospital). and some other tests also from laboratory. so i want to know that is it right to carry my consultation from this dr. or try another one ?
