I have thought that I have had OCD tendencies my entire live, mostly making noises, but now I have started doing something else. I have started rubbing my head, almost massaging my scalp more often then not. I find that I am, as nasty and weird as it sounds, looking for dandruff to rub off. I still make noises from Vocal Tic Syndrome, I cough, but this has become more prominent. I don't know if this is similar to Trichotillomania, but it is getting quite annoying.
