About a month ago, red lines or patches started to appear on my skin. Hands, wrists, feet, ankles, waist line, legs, arms. Very itchy. then they go away. The nurse told me it was hives. My doctor told me it was scabies. I bought Nix cream and used it last Tuesday but nothing has changed. I have been washing and drying clothes, blankets, sheets and am really tired of this. I I don t think that s the right diagnosis. What do you think?
