A very large percentage of people with anxiety have been tested for MS. There are a lot of similar sensations with both illnesses. My doctor originally was convinced that my symptoms were not related to anxiety and may be MS. This is the best approach. If you think that you may have MS, tell your doctor. If your symptoms fit the profile then he can begin testing to rule it out. Always rule out the possible physical causes first. As it usually ends up, it is anxiety. Better to know for sure. At least you can cross that off your list of things that make you anxious!
Those of us here know quite a lot about anxiety and we can understand your fear about MS. Unfortunately, most of us don't know enough about MS to really give you the help you're seeking. Please post your concerns and symptoms on our MS Forum. The folks there will understand not only your anxiety, but will be able to give the very best advice.
I'm sure you're fine, but go talk to the people who really know.
We'll always be here for your anxiety issues.
Peace
