Hyperhidrosis in palm? What technique is used?

My daughter is 13 and has palmar hyperhydrosis. We are considering Botox treatments? Any other suggestions? We've tried anti-perspirent on her hands. It doesn't work very well.

I begin sweating profusely anywhere at anytime for no reason on my face and head. My hair gets very wet and I have to carry a dish towel around to wipe my face. What can be done about this?

I have excessive sweating in my hands and feet and desperately want to find a solution to fix this problem. My hands are constantly clammy and my feet are sweaty and cause them to smell horrible. Can you please give me some advice?

Can this help with hyperhidrosis in hands and feet?
