I have pain in between my both chests. If I do running or walking, I won't feel any pain, but I feel pain while doing surya namsakar and sometimes feel tightness in the same area. I have been facing these issues from 3years and showed to the multiple doctors and done 3 times xray nothing found in x-ray. Asthma test also had been done every thing normal but pain not going anyway. Your input will ve really help me
