Could this just be stress or...?

Yeah it could be anything!! Stress ezema dermatitis chicken pox a reaction even scabbies!! Go to A doctor is the best thing to do!! Not ask on here because even a doctor would have to see this rash before telling you what it is!! I've got ezema on my back I didn't know what it was and because I was young and didn't tell anyone it got all infected nothing worked on it and the doctor had to look it at that give me tabs and creme!
