Of course it's all in your head, most neurological illnesses are.

I hate it when Docs say that.
The short answer is yes, you could have MS or some other neurological disorder? In time, if it hasn't already, anxiety can and will trigger an attack of MS....not exactly cause MS but close.
Ask your Doc to cure your anxiety disorder to see if your other symptoms disappear. If not, then it must be in the Docs head and he should go back to the drawing board.
Take care and try to stay as calm as you can. Check back with us when your Doc wakes up..
