question: Hi, may I answer your health queries right now ?  I have been experiencing back pain in the upper left shoulder blade for 2 weeks, pain is now traveling down my left arm and arm is pulsating.  I am thinking the pain in from a new workout i started 2 weeks ago (kettle ball) but want to make sure I am not having a heart attach. I have a chiropractic appt tomorrow to work out kinks in back.
