Maybe asking for a referral to an MS specialist would be helpful. In the mean time, gather up all your medical records from all the places you have been and for all the tests that you have had done. This is not only for your records but to give a copy to any specialist you see. Also, if you can, keep a log of your symptoms.

I am sure the physicians must know something is up. The next time you go in to the dr. bring someone with you, someone who has seen some of the symptoms you are experiencing. Sometimes those close to us see more than we think. At least that has been my experience.
