Thanks for all the help!
I'm fairly certain I have some hormone issues.
Seriously, my tbi, my brain bled (subdural hematoma) was located just adjacent to my brain stem, and I'm certain there are some important glands there, pituitary, etc.
It was after the tbi that this odd sweating started, on my head.
I had the rsd perspiration before, on my hands, feet, if I took off my socks...
I know also, just by the "side effects" that my testosterone is low, I used to use a supplement, it just didn't seem so important after a time.
So, I do have a perscription for some serious blood work, which, may lead to more.
I'll show my doctor your suggestions!

I usually take a luke warm bath, then follow with a cool shower.
I often take some pain meds, (methadone) before I shower. I'm going to start watching what triggers it. It just seems that my pores won't close on my scalp.
So, I'm done with a blow dryer.
And, I usually drink something cold, and even sit in front of the A/C, in an attempt to close my pores.

Thanks for all your great suggestions.

I'd appreciate any more, and let ya'll know how this works out...

love to all,

pete
