Not sure if you're still reading this thread, Joe, since it's been a couple of months.
After reading Rick's original post, I was *very* glad to see you up and posting... (I *do* believe divers tend to feel empathetic pain of fellow divers as much or more then any other community)...
I realize the only way a space occupying lesion (spinal bubble) can be definitively diagnosed is by examining the cord itself, I was wondering if your docs had given you any empirical data supporting their diagnosis, in light of your textbook dive profile.
I saw in your thread that you'd had a malt six-pack, and a tequila the night before, and was wondering if they cited that as a factor (resulting dehydration?).
Anyway... bottom line... I was greatly relieved at your recovery... Hope you are/will be cleared again for diving shortly...
