I have been having sharp chest pains for a few days now. Usually when I straighten myself out. Any time I straighten myself out I get a pain in my chest and my left arm, or if I sit in certain positions. It is probably some muscle relate thingy. Should I bother a doctor with this if it is still there come Monday?

I am a smoker, who doesn't excercise. Ages 23. I have asthma and have had problems with severe chest pains in the past. It is probably nothing, but I've heard that chest pains that spread to the arm can be potentially bad news. Is the doctor still here lol?
