I think I have this! I've noticed after a shower I've suffered intense itching/burning/crawling sensation in my skin after a shower. I be used soap-free products, only washed hair and necessary areas (!) but it still happens. There are no red marks, no lesions or obvious signs of skin trauma. It jumps around my body from thighs to arms, shoulder, feet, etc etc for up to an hour. I've moisturised but that doesn't relieve the itch. I've even told people "excuse me slapping my skin, I itch for an hour after a shower and slap my skin to counter the itch". If I mention this to my rheum will it be related to lupus or is it just random?
