OK, here's a good one from a few years ago. I was diving with A.N.Other , coming up from 20m. All went well with a nice gentle ascent until around 12m when he started to get problems with buoyancy.

Now: he was in a drysuit; he did the appropriate things to deal with air in a drysuit - roll to get head up and open shoulder dump. At the same time, I was holding on dumping air and doing all I could to slow his ascent. We both hit the surface after a fairly rapid ascent.

At the surface it turned out that the problem had been the LP inflator on his BCD sticking open.

The moral of the story: remember you have TWO possible problems with stuck valves if you're diving a drysuit.

Also: He got bent. I didn't. We had the same ascent (maybe I'm a bit of a tit for risking my own safety here - make your own choice) - clearly different people at a particular point in time have different susceptibilty... I was the lucky one in this case. He had no symptoms immediately after the dive but felt pins'n'needles in his left arm around 12 hours later. He had the good sense to get to hospital rather than ignore it. One trip in the pot sorted the problem.
