Please help !! In the past month I have a break out of something like raised knot like areas that itch and burn , the itch is so intense that I have dug Mark's in my head I have lost a quarter sized area of hair from scratching. I will wake up with blood under my nails from scratching during the night. I have bought every shampoo for itching, psoriasis, eczema bugs , fungus, you name it.nice spent over a 100$ on stuff and nothphelps. Is this RA related? I don't insurance so I don't go to the Dr much but I think I am going to have to. It's just a clinic that is income based and they are not really invested in patients care. . Sorry for rambling,, I'm just really tired of itching and burning..
