I found that after a tough workout or long run, i get a sharp chest pain in the center when breathing deep. it goes away after a few minutes. ideas?

Eval needed: Talk to your doctor about this. It may be related to the heart. In this case you may require additional intervention.

Rib pain: The strong workouts can cause rib strain and when u take a deep breath, the muscles move causing the ribs to move and hence the pain. If you have associated wheezing or shortness of breath, that needs to evaluated.
