May also be an anxiety thing... when I go through extremely stressful time with work/school my feet sweat!
With hyperhydrosis I believe the symptoms occur all over your body, primarily underarms. It seems odd that hyperhydrosis would remain specific to the hands but I'm sure its possible that there is some sort of condition out there which causes sweaty hands.
Some medications cause out of control sweating. Have you been taking any medications since the symptoms started?
There's all kinds of quack-cures being advertised out there, so be careful following any of them. I would say, see your doctor, and they can advise on real treatments that actually help and aren't scams.
