Many of us have exacerbations after sweating. I always simply wash with a wet washcloth (any temperature) and dry. Some people use witch hazel (it evaporates easily.) I have taken to using a hairdryer to dry all my creases after showering or any time I'm wet. I find that if I don't do that, I can get quite itchy, with or without a rash. The creases of my body tend to stay damp even after I dry with a towel. That includes the little dip above my clavicle, under my breasts, even though I am very small, where my thighs join my torso and even my butt crack and crotch area (sorry if TMI - it might help someone.) Where there's still a rash (which happens now only occasionally) I use a few drops clove oil mixed with CeraVe cream. Just make sure you wash your hands thoroughly after using clove oil because getting it anywhere on your face or near your sensitive eyes or mouth not fun. When I was in a full blown rash, I used clove oil straight. It burns so good (vs. itching so bad) and made the rash recede. I have posted this before, but insert here for newbies. Now I get an isolated bump in any random place on my body that itches so intensely, it almost feels like a bee sting. The clove oil, straight, makes it go away.
