OK so a lot of times when I drink mountain dew or other dinks I will start to get chest pain. The pain verys sometimes but I can't get a normal breath in. I sometimes have the same problen on when I eat. I work out everyday and eat pretty good. Does anyone know why I'm having pain?

It might be beneficial to have an EkG done. I would stop drinking caffeninated drinks for a while too. You could be allergic to an ingredient found in Mountain Dew.
