What Causes Pain On The Left Side Of The Body?

Hello Dr, I have been experiencing some pain on my left side today...my arm, shoulder, back of shoulder and neck along with some tingling sensation in my left hand and fingers and am very concerned. If this continues into tomorrow, I am planning on possibly seeing my physician who is also a cardiologist. I would appreciate your thoughts. Thank you. Ann Anastos Ann. Anastos @ yahoo.com
