I took a very mild DCS hit (skin bends) about 3 yrs ago. I was doing some rather aggressive cave diving (1-1/2 hr long dives to depths of 90ft) at Jackson Blue. As the week progressed I slowly became dehydrated. On day 5, I exited the water & within 30 min. or so began to feel a prickly itch between my shoulder blades. I had been wearing t-shirts all week, so knew it was not sunburn. On that 5th day, I was loading cylinders & equipment into my truck (buddy had gone to the bathroom), when I suddenly felt very light headed & completely exhausted. I was so tired I could not even hardly move for more than 10 min. My buddy came around & saw me & asked what was wrong (he’s a physician). I told him & we went back to our rental trailer. I drank a lot of water, rested a few hours & was much better. I wasn’t 100%, but doing better. My buddy kept a close eye on me for a couple of days & I became stronger & better. A close call. I really watch & make sure I take in enough fluids when doing a lot of "power diving".
