sweat a lot under my arms. Doctor, can you tell me how to limit and stop sweating under my arms?

Hemifacial spasm is characterized by involuntary unilateral contractions of the muscles innervating the facial nerve. It is a benign condition but can cause significant cosmetic and functional disability. In addition to microvascular decompression, botulinum toxin injections are more commonly used to treat hemifacial spasm.
