Welcome Rob.

Are you seeing a Neurologist? Have you had all of the tests for possible MS? If not then you should and if so and nothing pointing to MS has been found, then you're on the waiting list, so to speak.
MS is sometimes difficult to pinpoint and diagnose, so after all the tests, we wait and see.

It's exasperating but, sometimes, the name of the game.
In the meantime your Neoro or PCP can treat your symptoms, I would think.
Take a deep breath and try not to stress out, as that only makes symptoms worse.
