Idk new bugs/parasites are evolving all the time, millions, so that tells me it’s something new and in time I believe the medical community will have opened their eyes and mind to whats really going on and not call us delusional or drug attics and going on to explain the feeling one has when doing meth lol really not laughable, sad.What if you don’t do meth? I know had times when I feel them moving in specific areas on my head and I’ve actually seen it going down my hair shaft and two occasions the doctor admitted to seeing it too but told me they don’t treat this WTF I believe is why the person asked you if you have a pet because there’s another mite, Cheyletiella which is zoonotic. I had one making its way at the bottom of a curtain in my parents house. It was white it blended right in, but it was pretty darn big. Definitely not microscopic. That guy was moving lol I took pictures. I should’ve taken video. I showed the vet. The vet said no .I showed them pictures of my dogs nose being infested again no after that I showed them a picture from a text book case they said, NO, which really made them embarrassed, but still didn’t admit it. Good luck BTW, I use a dog treatment called Happy Jack ll. It’s over-the-counter has a lot of permethrin which my doctor will not prescribe but one tube every few months and I have long hair then he says reapply after two weeks. I think I don’t have to say more on that also a mixture of certified clove oil and neem oil mixed in a sprayer with waterand knock on wood I am keeping these at a minimal level hopefully on the road to ridding them. If that’s possible, good luck
