I have really itchy spots on the back of my skull, from shingles. Since the shingles numbed the area where they were, it is easy to scratch too much and not feel it and make it worse. Same would hold true for an itchy spot resulting from Mohs surgery. I put on mittens and went to sleep...and woke up with the mittens off and "catching myself" scratching really hard! Any ideas welcome! Ronni (skincancer.net moderator)
