I have a rash that comes and goes, usually it starts with a burning sensation before getting really red. I ve taken some pictures of it, sometimes it s patchy and sometimes a series of pinpricks and it seems consistent with scabies. But the rashes tend to stop itching and go away within an hour or so when I rub alcohol on them, which I ve been doing for the past year. I did three rounds of permethrin and cleaned the house thoroughly, and still it seems it won t go away. It usually reappears within a couple days to a week at most. Could it be scabies, or something else?
