I have a several different spots on my body: shoulders(front and back), forearms, top of hands and top of feet, that start itching completely out of the blue. I try desperately not to scratch but I end up having horrible spasms and the itching becomes so intense and horrible I literally caused deep scarring from scratching with things such as a hairbrush in the attempt to stop the maddening itch. The only thing that helps, after a while, is freezing the area. I can find no precursor to these itching fits. I have tried all types of medications, lotions and oils. It is so bad that there are times that I have to restrain myself from getting something very sharp and either scraping my shin off or stabbing myself where the painful itching is. There is also no rash. Could this be neurological? It's been going on for years.
