Thanks, I called DAN, but they couldn’t give me an answer. They said most diving incidents show up as a rash, which is what the head Dr, at the Cozumel emergency hospital told me. The first Dr I saw thought I might have a perforation and mentioned exploratory surgery. I was so relieved, they were no longer talking surgery that I never asked him what it might have been. (it had dissipated before I finally got in to see the Dr.)
I’m very curious to see if this has happened to anyone else. Maybe it had nothing to do with diving but...........
