Extreme Chest Pain
I just came in from a run and at the end of 30 min the left side of my chest seized up and it felt like I got shot. I had this before and it was after about the first 5 min but it was in the same place only on my back. I think it might have something to do with my lungs because it hurt when I breathed out but not in. But man did it hurt. Now, its about 15min later and I feel great. Muscle spasm? Heart attack?
