Stop smoking and had a hysterectomy in September. Shortly after I began to have a uncontrollable and unexplained itching that at first we associated with nicotine withdrawal but 4 months later I m still having an uncontrollable itch and now bruising on my thigh area. My hysterectomy was due to endometriosis and some was found one my liver. Should I be worried that this is more than nicotine withdrawal?
