I thought the same as you, and mine started in October. I just thought it would pass but here it is almost March and still the same. I am numb from scalp to fingers. Saw my Neuro yesterday and he is scheduling 3 days of IV steroids next week.

Basically my neuro said, Ms is so unpredictable, anything is possible. I too have never had a exacerbation and everything has been slowly progressive. So Im hoping this Steroid thing will help. Good luck.
