I've had a problem with this rash ever sine I went keto in 2002, it first it was sporadic and I blamed it on sweating from exercise but I eventually realised it went away if I increased carbs. I had tried fungal creams, powders and antihistamines which didn't work, cortisone cream helped but it wasn't a long term solution. I have spent the last 12 years keeping my carbs to a point where I keep the rash at bay. If I feel it coming on I know I've let my carbs dip too low and increase them. I've had this rash come on after a bad fever also. I decided to have another crack at very low carb, I'm up to day 7, after just one day the rash was back, its driving me insane. It's on my eyelids, eyebrows, scalp, upper abdomen, back and sigh the pubic area. Really sucks because I love keto! prom party outfits in dark purple
