Pass the pain relief ointment
On a liveaboard in Verde-Galera, one dive buddy (who also happened to be a doctor) once pulled out a splint (!) to try to immobilize my wrist. Because...on my way down from the mess hall to the gearing area, I slipped on the wet steps and my arm instinctively shot out in between the metal railing to steady myself; I hurt my wrist instead (just the memory of it still makes me go oooouch). I opted for his tube of inflammation-reducing, pain-relieving ointment instead, and submitted to the DM's help in gearing up (like a child being dressed), just to go on two more dives (cold compress, right?:D) despite a frightening-looking blue-green hand -- foolish, foolish girl :D
