The overall dryness that those of us on the spectrum experience is especially prevalent and painful in the ears. It is our lot in life. I have had problems with my ears since I was a kid: water in them or swimmer's ear, excess wax that cakes up, the odd ear infection that has required a visit to a specialist, etc. I started out using q-tips; I better not reveal what I do now. I'll just say that we have to resort to some extra measures to get some relief from the pain, itching, heaviness/fullness, rumbling sounds, and so on. I can't make any recommendations, just let you know you are not alone for sure.
