Everyone is discussing wrinkled fingertips. Just a few questions of anybody/everyone:
1/ Do you work with companion animals/livestock.
2/ Workout in a comunal gym/exercise room.
3/ Are familiar with how foot fungus feels. Hot, burning, foot becomes reddish, glazed and some wrinkling of the underside of the toe.
I have been reading and the same fungus on the foot can affect the hand. My hands were blotched, hot and had severe wrinkling of the fingertips.
My new guess, since I am no doctor, and people have actually written about Canida (spelling error) is that fungus can be a potential cause of wrinkling and one should potentially consider if you have a fungal infection on your hands.
Just my wild guess...........
