My wife is also a scratcher and she is doing painful damage to herself.

I have tried all I can think of and at times I have her covered in so many dressings that she looks like something out of the mummy's tomb. I have been to the GP twice already and she is presently on a course of antihistamines to stop the itch cycle with the scabs. The next thing the GP suggested was a referral to a dermatologist (something that was also suggested by her CPN). We have the third GP appointment next week. Creams and an increase of her anxiety meds only worked for a few days.

I have resorted to keeping her nails short, putting gloves on her at night and watching her like a hawk while I'm awake. It's a difficult problem as she denies that she has an itch and even denies scratching and picking at herself. She has the look of a naughty child who has just been rumbled when I catch her in the act! Oh the fun and games.
