I'm just picking at straws here ~ Have you checked to see if any of your meds cause increased sweating? Some meds do, as I've found out myself. It can be pretty darned annoying, as you well know!!!

Perhaps your pharmacist can print out a sheet of side effects you can expect with each drug you're taking. I usually get one when I start taking a new drug.
Like I said, I'm picking at straws. I can't think for the life of me what would cause this, as you've already had checked, the things I would have suggested.
I sure wish i could help. Best of luck, and God bless. hugs, Lee
