I suffer from excessive sweating too and had my scalp injected with about 50 shots of botox. I think it helped my sweating but my face just dropped. It was as if my eyebrows and eye lids had nothing to support them!! Very uncomfortable. I am now planing on having it injected on the back of the scull and see if it helps at least in that area without affecting my face. Wish me luck .... or why don´t you try it and let me know???
