Hello. So increased sweating is a condition called hyperhidrosis. It can be idiopathic (no cause) or sometimes associated with a thyroid disorder.What you can do is get 1-2% formaldehyde. Using a paint brush, brush little quantity on your palms and feet every night. You will get a symptomatic improvement. Another option is Botox injections which will give you a disease free interval of 4 months, but are slightly expensive.
