Hello, I ve been itching now for about 3 weeks, it started in the center of my back and under my shoulder blades, now its the back and front of my neck, arms,hands, etc. I can be sitting watching TV and feel a little itch, scratch it, and it really starts itching after that. I ve changed sheets on our bed, vacuumed and dusted the whole house thinking it might be fleas or something like that. Even after a shower I itch.
