Hi, over the past several weeks I have been scratching my skin to the point that it welts. The welts are gone the next day. But the itching comes back. No change to diet or soaps or shampoos. Been on a dlet and quit drinking alcohol for just over a month now. Drink lots of water and eat fresh fruits and salads. I am not sure if stress is causing this or something from the absence of alcohol. First break in many years of a drink maybe two a day. Just decided to take a break. Do you have any ideas?
