I am sorry you are stuck in limbo right now. You certainly have some disturbing symptoms. Have you had the usual MS tests? MRI, lumbar puncture, evoked potentials?
The leg paralysis sounds very scary. I am glad to hear it didn't last long. What about your other symptoms? Do they come and go? Are the symptoms you describe things you have been dealing with consistently for days, weeks, months?
Most MS symptoms are fairly permanent. I have chronic vertigo and balance issues. I have had them since I before my diagnosis. I have numbness. My feet and lower legs are numb...........every minute of everyday.
Some do have some variability with MS, but for most of us, the symptoms we have are from permanent damage to the brain or spinal cord.
Please keep us posted. Ask as many questions are you would like. I hope you get some answers soon. I hope it is something treatable.
