I think I have a rare disease of the skin. I thought it was head lice , so I applied everything nix, rid,vinager, etc. I went to the dermatologists x2 the first one said i was allergic to the sun,the second one said it was allergies. I think its scabies. I cant stop itching and I have the cough, the hot flashes, I seen flakes fall off of my head like it was a dandruff flake\ color grayish. I applied permethrin cream and it helps like 95% but I can t seem to get it out of my hair, eyebrows, ear, and nose. I had the s shape on my ankle and the dark skin between my fingers and toes. I went to see my primary physician told him the same diagnosis and he said basically I just need to relax I know when something is biting at me and I seen my hair move yet I couldn t find anything crawling. that s the problem I don t see anything but I can feel it. im about to cut my hair off. please help could this be something internal? what is it.
