Hand sweating is the tendency to sweat profusely without a specific cause, usually on the soles of the feet, underarms, head and face. Hand sweating is caused by abnormal hyperactivity of the sympathetic nerves that control the sweat glands, and generally does not heal on its own. The best treatment at this time is surgery at a regular hospital to cut the sympathetic nerve chain to eradicate the problem of excessive sweating. The side effects of surgery may lead to increased sweating in the front and back. Antiperspirant medication can be considered for treatment, but it does not cure the symptoms and has side effects with long-term use.
