I have bad chest pain, shortness of breath and now my arm gets numb when this happens. my doctor said im fine though?

See below: How old are you what meds are you on what does your ekg show and chest x ray. You should have a stress test if you are having exertional chest pain (with exercise) what is your blood pressure if elevated is a definite risk factor.

Not fine enough: I don't think you are fine enough -- so find another doctor or get a second opinion and get yourself evaluated again!
