Today I got a sharp chest pain for 30 secs while sleeping in night, in this 30 secs pin was going and coming. Later I felt to passing stool after passing stool I was relaxed. Later on too much burping started. 2 weeks back I have done ecg, echo and tmt, the result were negative. Whenever I feel chest pain/pressure I feel to pass stool. Is this cardiac issue, if not which Dr to show.
