I am 56 years old male undergone Angioplasty five years back due to severe attack and was put two stents. I was alright for first 15 days and thetesfter, I have been suffering from pain at my chest continuously. at times, pain is like pinching, sometimes stabbing like and sometimes hammering like. I am not able express the exact nature of pain and particular point. I have undergone many tests viz, ECG, Echo, Xray, TMT etc. Several times with famous Csrfiologists, reports are negative. But pain still persists 24/7 through the yesr. Doctors have prescribed many medicines to get rid off the pain like Zerodol, Dulane, Xykaa, Amunarite, but in vain. Further, I have been taking clopitorva 20 mg a tablet each every dsy snce Angioplasty as prescribed by Doctors. During April end this year, to clear the doubt, Doctor suggested to undergo Angiography test which I underwent in very famous KLE Hospital, Belgaum (I reside in the same city in Karnataka) and report is normal. L. Further, I approached Apollo Hospital at Bangalore last month and they have suggested various blood tests like Vitamin. D, calcium etc. But all the tests are within normal. When all the test reports are normal, why the pan remains that too intolerable. I am living in fear day in and day out. I am totally frustrated due to unexplsinale, intolerable pain. I walk around half an hour daily. I do not get good sleep, due to which I am developing weakness. I am vegetarian and take good diet. My BP is normal and am not diabetic. Please suggest proper solution.
