I like all the suggestions here and am just chiming in to give my two cents. EVERY year I get a heat rash where my underwear meets the creases of my thighs. Every. Damn. Year. It is red, itchy, and just gross. What works for me is first wearing underwear where the elastic around the legs is covered in fabric or made of fabric - not plastic. Also, just plain wearing underwear so my clothes aren't rubbing against my body helps. When the rash comes around, I put a thick layer hydrocortisone cream on the effected area and sleep without undies. I usually do this for a few nights and it goes away. Also, I diligently dry the area after showers. I have noticed that if I don't I am more susceptible to the rash.
