Welcome to the boards.
I would recommend seeing a neurologist who handles MSers as a specialty. (My neuro does MS and ALS). I think that you will get a better diagnosis. As to the Neurotin, if you still take it, you need to get weaned off of it- do not stop it or you will likely have issues.
While anxiety could very well be the root of your problems, a MS doctor can help you sort it out. Anxiety can often manifest with MS symptoms. If there is indeed anxiety, your neuro will treat that in order to have a better idea of your root problems.
