"I am having a sharp pain in my left side chest (under the arm area directly left of the heart), and then my left arm begins to tingle or gets numb. This started yesterday and they were about 45 minutes to an hour apart, then late yesterday afternoon they started happening much more frequently, 5 to 10 minutes apart Does anyone know what the symptoms are telling me? I am 55 years young, and it is kinda scary to me to be honest. Yes, I really don't like going to the doctor."
