Repeated episode of sudden sharp pains in chest, back near shoulder, difficulty in lifting arm. Cause?
I am 46 years old and this is the second time this has happened in two weeks that I just all of a sudden get a sharp pain like a cutting feeling in my left chest and a sharp pain in my back up near my shoulder kind of in the middle, this time since it happened the pain just went away in my chest but it still hurts in my shoulder area. It hurts to lift that arm now. What could this be going on?
