I have been to many dermatologists since I was younger. I have some sort of hyperkeratosis on my left hand and left foot. My doctor continually shaves it down and it grows back after a couple months. It is slowly spreading. I believe it may be"Focal Acral Hyperkeratosis". I'd like to become part of a research study or even find some sort of treatment that may help. Please let me know if you have any advice.
