I get these itches too, one time it's a toe, next time it's across my back, next time it's elsewhere. Drives me insane. Nearly always when I'm trying to go to sleep. Sods blooming law. I end up trying to cool the area down, doesn't always work. Got several itches going on as I type this eyebrow, hand, knee arghhhhhh which to scratch first? I bought cooling gel from body shop which sometimes helps as does aloe vera. Magicool or Boots equivalent is handy to have too.
