So for past days blisters have been forming on my toes, hands (see pictures). Also I have started to get scab lesions on my scalp that flake when picked they are a bit itchy but more sore. The blisters on my fingers and hands are very itchy more than anything and blisters on my feet where I'm finding it hard to stand on them. Really concerned as to what's going on? Anyone had this before or going through it? Any recommended treatment?
