In early 2014 I had a heart attack, heart cath. and a stint was placed in my heart. Nine days later I had a second heart attack and a second stint was placed. There was a third heart cath. performed a month later as I was in the ER again believing I was having a third heart attack, the stints wear in place and everything looked good. Since then I am having pain almost on a daily basis, my Doctor is baffled he is unable to relieve my symptoms with medications, I just had a stress test, 3 minutes in I was experiencing left arm pain, shortness of breath, and chest pain into my back, yet my EKG showed nothing? Is this normal? Could this be something other than the heart? Could this all be in my head?
