I am having chest pain for last 2 months sometimes on left and rarely on right side. I have gone through many ecgs they came out to be normal. 2D echo is fine as well. Trop-T is negative as well. And I don't feel any pressure while walking or doing exercise but the pain suddenly comes and is very sharp. I am suffering from hiatal hernia. So what could be the reason of the pain and the pain also radiates from chest to abdomen and hands and legs.
