Should I Get a Brain Scan for My Symptoms?

I did and it gave me piece of mind.

Like Royalty said, it depends on the onset and severity of your symptoms, and whether you are medication resistant.

I guess that depends on when your symptoms started. I'm probably not the best person to respond to this because I also have OCD and can't really give a good answer because of that, but I'd say get a second opinion from a professional and go from there.
