What might cause a dime-sized, painful red spot to suddenly appear on my boyfriend s back, near his right shoulder blade, when I rubbed a few inches above it? It immediately disappeared when I released the pressure, then reappeared, when I pressed again. We had been at the drive-in theater. His arm was resting on the passenger window and, when he lowered it, his shoulder started to hurt so badly that we had to leave, because he needed an ibuprofen. The pain migrated to his neck and back, so I tried to relieve it with a massage, when the bizarre, painful red spot started appearing and disappearing. When I pressed near the right side of his spine, a few inches below that, he felt a warm tingle or twinge, that almost itched, but then became something like a tiny muscle cramp, and it reminded him of mild shingles pain. I was going to video tape it but it suddenly hurt too much and we both were afraid it might be some kind of aneurysm. It s not raised or warm at all, and it went away completely, when I stopped massaging. Now we re freaked out. Thanks for any advice you might have.
