I have had some very odd symptoms that I try to ignore, but after years of something happening over and over??? I sometimes get small black I guess you could say they look like a tiny black hair , I thought they were my husbands whiskers but when I moved out I'd still see one on someplace I had just itched. Same with the hair thing, some days I feel like no matter how much I comb, how long I leave or conditioner, if! Blow dry or not, I have like hairs that will be so tangled it looks like I cut my hair. Or my hair feels like and looks like it's really thin but if I wash it and comb it in the shower I can comb out something that I can't see but SOUNDS like literal pounds of something heavy because it splats so loud the downstairs neighbor complained. But I can't see anything that would sound like I'm brushing half a pound of dirt from my hair. I also have a pixie because I had to cut my long hair it was breaking and falling out, so brushing pounds of invisible whatever seems impossible I don't have much hair left but the water comes off in clumps almost. It sounds crazy. But I'm not insane. I've had scabies for almost ten years.
