You got some great advice here in August.

Were you able to act on any of that? I'm so sorry nothing has resolved since then.
Do you have a regular doctor at all? if you do they can do a neurological exam in their office. It reflexes, following a finger with your eyes, etc. From that simple test they can tell you if you need to see a neurologist or not. Even if you do not have insurance it would be worth it to pay for an office call to rule Neurological in or out. If the test is normal you can definitely put MS off the list.
TMJ and Fibro in themselves can make you very miserable.
