It seems to come and go, but when I do feel it, it ranges from a sharp discomfort to a mild tightness and it's always in the same place, it never moves. It is in the left
pectoral, kind of in the middle, upper
About 12 years ago when I first noticed it, I went to the doctor to get it checked out. They did an EKG, blood work, x-ray, stress test etc.... and everything came back normal.
I do NOT feel the pain when I am exercising.
