I have some type of iching, burning rash that develops on the palms of my hands, fingertips, and the inside of both feet in and around the arches. It is more severe on hot, humid days as I live in South Alabama, but the rash also seems to flare up when I am stressed, nervous, or upset. It has been going on since I was in my 20 s, 33 now, and it seems to get worse every year. Any suggestions as to what it is or how I can treat it?
