Had 2 way bypass in Jan, third artery was "dried up" and couldn't be used. Have had occasional burning pains in my left arm since. The pain starts over my chest and moves out to my arm. Have also had numbness in my left hand which was diagnosed as a pinched nerve but wasn't told anything to do. Surgeon told me I would have shooting pains as a result of nerves in my chest healing but am not sure which pains are considered normal
