Welcome. MS is a common one and you have many of the symptoms. As was said above, there are so many others that can mink MS. I was wandering if you have vertigo or memory issues? When you had the problems, would resting will awake make them better? Was there any head pressure, headaches, light sensitity? I would get copies of the radiologist reports. You can usually get them from the imaging center. They sometimes say minor things that the Dr will not bring up and they later become larger things like mild ischemic areas, sinum impactions.

Some dx take a long time because they dont find some things right away. Try not to panic over it, just keep trying. The insurance is a little strugle. I would eventually recommend the spinal tap. My Dr did it in his office by him self with no imaging. He was very good at it.
