I have had, for the past 3-4 days, chest pain that comes in segments lasting no more than 3 seconds at a time. It happens regularly, on both sides of the chest. The day it began I remember eating my food too fast (barely chewing). The same day I went to run, but a few seconds after I began, heart pain stopped me. Every time I started running, it would start again, so I had to walk home. (Walking was OK). About 2 days later, I thought it had passed, so I took another try at running. This time I was able to run for about 10 minutes, but after some time the heart pain took me and again lasted for the whole exercise session. I didn't go running since then, and now regulary every 1-2 minutes I get light - medium 2 second pains around my chest area.
