I have been having about two or three spots on my back that are extremely itchy to the extent that it is driving me crazy. It started with one spot and I had my husband and daughter look at it several times a couple weeks ago but they said there was nothing there. Feels like I is deep like in the nerve. Yesterday I had my son but a anti itch liquid on the spot you have to push on the tube alittle and then rub it to get the liquid to start flowing. I about jumped through the roof when he pushed alittle it hurt really really bad. Only thing I can think it would be is maybe shingles but there is no sign of a rash of any kind
