I have the same kind of under the skin itch "the mad itch" I like to call it. It seems worse in the summer, but I have had it in the fall. I first thought is was from the sun and it may be. I have tried everything over the counter and my doctor prescribed an ointment, but by the time I had the RX filled the itch had stopped. The only thing that gave me enough relief to sleep is to get one of those gel ice packs and wrap it in a cloth napkin. That eased off the itching enough for me to get some sleep.
