Re: leg weakness
Make sure you get a c-spine MRI
I've had no pain through my ordeal. Started with arm swing and walking (gait) issues. Progressed to muscle weakness, all on my right side. C-spine MRI showed "severe" compression and I had surgery three weeks after the MRI. 16m post surgery I'm 70% ish better, still have gait issues and some minor tremors.
Good luck - stay calm - find a doc you trust.
