I've had this rash about 6 months and I'll give the full details and a picture on it in hope that someone can help get a diagnosis. I have already been to the doctor once, diagnosed, and treated for scabies 3 times now and it's still there.
The rash started around March just under my arm, on my armpit. I pretty much ignored it hoping it would go away. The opposite happened, it spread to the middle of my arms on both sides in the creases and on the elbow, my groin which was the worst, and also my thighs and buttocks had the rash. It was a red rash with small bumps and very itchy. It even spread to my fingers, small bumps would pop up on them and be itchy, although these were not red.
I went to the doctor, he diagnosed me with Scabies, gave me the medicine for it which was Permethrin cream 5% w/w. I covered my body in it that night, waited 14 days like it said, covered most of my body again, waited several months and covered my entire body. The rash changes a lot, even before the scabies medication started. It would sometimes disappear on its own, and sometimes come back worse, sometimes come back more mild. The scabies medicine really didn't effect it much more than what it had already been doing. I just used the last of the Scabies medicine last night because it started to spread on my lower stomache (picture). Also there's a patch on the inner-back of my thigh that's about the same. Any ideas?
