I have started to get these spasms too, but in the middle of my chest, up my back, between my shoulder blades and into my ear. Last night I had several attacks. I have developed high blood pressure but my blood pressure is not elevated when I have these attacks. I have been treated for acid relux/heart burn, but do not feel I am having heartburn during these attacks. I am in good shape and don't feel I was having a heart attack. It is interesting how our doctors can't concentrate in finding real cures for what ales many of us. I have spent thousands of dollars on all types of test for leg, hip, and feet pains and they have not given me an answer. Now I'm faced with this and I will not have them probe my chest. It is scary to think that maybe many people are having bye-passes when maybe it is just a spasm. Or is it scary to think that maybe these "spasms" or another form of heart problem no one knows about. Can our hearts go into cramps not caused by clots or blockages, something not seen by tests or x-rays and we can have a serious outcome? I am exhausted after just one of these spasms.
