Hi and welcome,
Aarcyn had given you great advice. you have to be in control of your health. Don't let them blow you off. You have symptoms, yet unknown, but you still need to find out what is causing them.

A Neuro in a teaching hospital would be a good choice. They see all kinds of different presentations of Neuro diseases and can make a decision on what tests you really need. It may take time. Write down the 5 worst problems that you have. Any more than that they blow you off, time wise.

Have records or test results with you so they can get an idea of what was tested for before. MS is a ruling out of all other diseases. There is no precise test for it. But there are many tests that can rule it in too.

Like a MRI of the Brain, C-spine, and T-spine. Then a Lumbar puncture with a same day blood test to rule out Lyme disease and MS too, in some cases.

I hope you find your answers, it just takes time.
