I didnt go to the mayo clinic, but wanted to share a bit of my experience.

The local MD took notes of all of my sx, and history, and said "i think you may have MS" and packed me off to the local neuro. The local guy said "you are too old for MS" went on to talk about anxiety, and saw my MRI has lesions, and so forth, but was not quick to hand me any hope. He was quick to talk about migraines, stress and how difficult it is to dx MS. Local MD said, he would prefer I get at least one opinion from an MS center, and packed me off.

The MS center which takes hours to drive to, repeats the MRI, repeats the blood work, and examines me on several repeat visits. From balance to vision I was examined. After a couple of visits, they sat me down and said "yep, you have MS, and have had it for many years." They went on to say that alot of MDs wont dx you past your 40s but what they are forgetting is that most of those dxd with MS have had it for years. It was not an easy way to get a dx, but I found at most medical centers that specialize in such things, they go far out of their way to move every stone to either definitively rule it in or out. either way, you will know.

Hang in there. its tough enough to be sick, but to not have answers can make you batty. I spent years being told I have migraines, and anxiety.
