How To Treat Uncontrollable Skin Irritation From Wrist To Hand?

Hi,

For the past six months I have been having uncontrollable skin irritations. First it started at the wrist with what seemed like an ant bit, causing a small hole and soon increased to the hand and than the other wrist and it itched for three months. Than one day it stop and the itching on the wrist bump went away as well. During that time I also started to have sever itching of the skin, like eczema, which I’ve had since a child but never severe as an adult in the past decade or more. Now I can't sleep at night or function without scratching. At first it wasn’t bad at night but in the past month, I can not get a good rest due to itching. Not to mention I had a family member move in with me who had contact with another person with scabies. I've researched and tried different soaps thinking it was contact dermatitis and it helped a little but than I started to have hives and whelping when I will lightly scratch myself. I mean even if I accidentally poke myself, my face will whelp as if I had a mosquito bite. I researched that, to conclude that I know have dermographic aka writing on skin. I am suffering and unfortunately USA doesn’t have free health care and I am without insurance and cannot afford to go see a Dr. even as a working citizen. Please tell me what my solutions are please. Thanks
