Since January, I had about 7 similiar episodes. Each time the pain
was severe, crushing, in the middle of my chest, radiating to both of my jaws
. 3 of the episodes were while I was performing physical activities. The others just happened, no real trigger could be identified. There was no common food involved, no excessive stress. Anyway, I assumed it was not my heart, took an asprin (just in case) and the severe pain would last about 15-30 minutes.
