It is very difficult to explain what I am going through from more than past 1 year...last year suddenly at night I was laying and I feel squeezed and pressure  in my chest between my breast area as day passes things start geting worse I can't sit due to discomfort in the chest I can't stand it feels like heavyness tightness I don't know what it is...I can't lay straight nor my left right so it was so weird discomfort I cant even put hand on my chest and sleep there is a different feeling...if I scratch my chest between breast area with my hands I can't do that I feel so nervous( man mai  ghabrahata hoti hai).infact when I ride on a scooty due to wind pressure if my cloths what I am wearing touches my chest then there is so nervousness tightness...during this all were happening I feel so much pain in my upper back...I have consulted so many dr but no one diagnosed it proper some says anxiety some says acidty some says nerve problem. xray is also normal
