I have OCD and whenever I have a reoccurring thought (phrase or idea) that continues in my head for some time I often get sick to my stomach. I asked my psychiatrist about this and she says that she thinks that I get sick to my stomach simply because OCD is an anxiety disorder. She seemed very unsure, though. I'm confused, because these reoccurring thoughts do not always cause anxiety...they are more often annoying.

Does anyone else with OCD suffer from a sick stomach when they have a thought that continues over and over and they don't necessarily feel anxious?

Just wondering if I should have a brain scan or something.
