Choking with dry cough. Bhi saktahu!

I have been facing choking problem. I also feel cough is there in right side of food pipe however it does not come out. also I have shown to one physician in bangalore. he ask me for ecg test which was normal and then he further asked me for TMT which I have to undergo. sir while sleeping sometimes I will wake up during night as if I am not able to breath and start walking and could not sleep due to fear of death. also I feel stomach bulging on both sides and on right side rib sometimes I feel pain. one day after returning from running 8n morning I felt as if something wants to come out from my body and could not breath properly. I am feeling as if it is not yet properly diagnosed. I was also advised by the NEURO PHYSICIAN doctor to take nexitoplus tablet which i took for one month. this above problem exacerbated after taking this medicine which I feel. mujhe khane ke baad dakar bhi bahut aata hai. Dr sab kuch upay bataye mujhe jisse nivaran pa sakun. delhi aa kar dikhwa bhi saktahu
