I am experiencing an intense itchy & burning sensation on my right arm. It comes and goes and not any particular time of day or night. I haven t been able to detect what brings it on, but it is intense when it occurs. Sometimes it happens several times a day and then I can go a day or two non-symptomatic. I cannot see any type of rash or other markings except a couple of areas where I just couldn t get any cream on it fast enough so I actually ripped my own skin. I.m using products like Bebdryl cream or Dermadoctor KP Duty, seems to be the only things that help temporaryly. Ice also helps too sometimes. Any clues?
