I have microscopic (what I think are) skin mites (small bugs) that itch on my scalp, legs, back. I have actually seen very tiny bugs crawling on my skin. I don't know how I got them and have itched for a long time. No evidence of bed bugs. Online recommendations include Kwell, permethrin, crotamiton, etc..
Are these all prescribed medications. If so are there any over-the-counter medications that might work. I don't have insurance and can't afford back and forth to a detmatologist.

Never mind.
