I'm often pretty amazed that the human body works at all, even on the surface. If you've ever had a friend in intensive care, with a doctor willing to explain what all those machines going "ping" are really doing, and what all the lab tests are checking for, it makes you want to lie down quietly for a while. A bit back I threw out a post about an aquaintance who reached his greatest depth of 120 fsw, and decided to get out of the water faster than his bubbles. At the time, I thought it might be a drug interaction; he was on antihistamines. That may still be a contributing factor. We had a good discussion then; no need to start that thread again. However, symptoms also sound like a cold narc, and are similar to what one diver just described. My friend has since dipped below 100' only once, very cautiously, and on Nitrox I, fresh from his nitrox course. Said he felt a lot better. Maybe some placebo effect. I'm not exactly sure what to tell him now, except to stay shallow. To perhaps start another thread, I have a question for our on line doctors: I crack my knuckles and sometimes my neck. I have heard that the popping noise may be due to the creation of a low pressure area in the joint, which cavitates a bubble out of solution in the fluid of the joint. I try not to do it after diving, but bad habits are hard to break. Since this bubble, if that's what it is, normally goes back into solution, where does cracking a joint after diving fall on a scale of good to bad? | You can't have everything.
