Do you sweat when it is cool outside? Do you sweat so much that you soak your clothes walking from one class to another? Your hands are probably sweaty because you are nervous. Hyperhidrosis is just what it says... HYPER... hidrosis. An extreme amount of sweating.
If the sweat literally drips off your hands and feet, you could be dealing with hyperhidrosis. It is a condition that can easily be managed with the use of medication. Just talk to your doctor, get the right diagnosis and start with the treatment.
