@sheila69wg, I'm sorry to hear your appointment with the neurologist didn't help you find any answers to what is causing your symptoms. Hopefully your upcoming appointment with your primary care doctor will be able to figure out what is causing your symptoms. Mayo Clinic has some information on Excessive Sweating that might be helpful - https://www.mayoclinic.org/symptoms/excessive-sweating/basics/causes/sym-20050780.

Have you thought about seeking help at a teaching hospital or major health facility like Mayo Clinic?
