I have been experiencing chest pain for approx a week now. The pain is over my left breast area and proceeds under and down my armpit. When I am relaxed it hurts more, when active I have dull ache. I am a 31 year old male.

Have you visited the doctor or ER? Chest pain is never something to just ignore. This could be Myocardial Infarction, Gallstones or a number of other illnesses.

Please see a doctor immediately.
