I have the same thing - i think its called Hyperhydraxia from a quick google search (would that not have been a more logical choice?
). Ive had it for as long as i can remember. Used to bother me loads...now it doesnt.
Ive taken to just ignoring it...if someone has a problem with shaking my sweaty hand they can **** off. Girls dont seem to have a problem with it and to be honist any girl whose not interested in me cos i have sweaty hands sometimes aint worth shi+ to me.
I see no reason to change this for the benefit of others and now ive got over it im glad i didnt invest any time or effort or money into 'sorting it'. Alot of peoples hands are sweaty from time to time so if anyone comes into contact with you they'l just think that its an occasional thing.
Although its not realy associated with worry - if your worrying about it in say the leadup to a handshake or something then its gonna be a bit worse.
To be honist i'd stop worrying about it cos i have and im getting on just fine
(had a goood weekend). I feel more sorry for my sister who has extreamly dry hands (exema) and they frequently crack and hurt her...which is loads worse!
If you want 'treatments' look on google. But i wouldnt worry youself pal. Noone cares.
