fingernail discoloration due to diving

(1/1)

padudle:
Hello All,

I get an unusual form of decompression injury every time I dive. My fingernails get white bruises over the lunula of the nail that become apparent as the nail grows out. These marks form on my fingernails every time I dive but never on my toenails.

I think there is mild bubble formation in the growth portion of the nail bed that slightly damages the newly formed nail. I think I never get the effect in my toenails because during ascent and safety stop my toes are a good 5 feet below my fingers.

I never notice any other kind of decompression effect.

Has anyone else experienced this effect? Does it mean anything?

I've been diving, and reading Dive magazines, on and off since 1979.  The only thing I recall is discoloration due to CO, and I doubt this is you.  I think you should call DAN and talk to them.  If you do, report back here so we all can learn.
