I need someone to help me on this subject. I CONSTANTLY am scratching my head, to the point I get little 'sores' and bleeding. My GP said to bump up my Prozac. Didn't help. I constantly 'pick' at my head to the point of bleeding. I have some type of prescription shampoo., but this is only a temporary 'fix'. The minute I find a 'spot' on my head, (which I call 'boulders')the picking 'cycle' continues. My hubby yells at me for keeping my hands in my head all the time, but I can't help it. It feels like little spiders are crawling all over my head as well as my body!
