Hi matt,

This is weird its I would have ever considered a disorder for me, I thought i was just a germaphobe, but reading that you also experience something similar it's making me think about it.

For me, I feel like I can feel the germs or 'dirt' multiplying in an area. Even touching coins from change in a store makes me want to scrub my hands. As you said with the coughing, if I'm in a queue and can feel someone cough behind me like the air hits my hair or something I will actually have to go home and shower.
I can feel the exact spot that is 'dirty' until I clean it.

I'll following along with this thread, to see if anything useful comes up.
