Itching

I read somewhere on here just a minute ago about itching but can't find the comment now that I'm logged in. I know Dr Temple Grandin has said that it's a problem for her. Is that an autistic thing? Is it my brain overreacting? It's been a problem for me since I was in my 30s. I've complained to landlords and moved out of rented flats numerous times because of the itching. Is there an official respect-inducing name for this problem which I can tell my doctor and be taken seriously?
