What are typical heart attack symptoms? I just noticed a mild ache in my left shoulder blade, but I have been doing quite a bit of lifting and carrying the past few days, so it may be a strain. I also noticed a few hours ago a slight numbness in the skin of my arms. I m 67, in generally excellent health, fairly fit (walking, lap swimming most days half mile to a mile), but I seem to recall having heard something about these symptoms in the past. I have no chest pain, no arm pain, no shortness of breath, no sweats. Not sure what else to say.
