10 months left side arm leg weakness, numb, hard to walk, now it is getting better, numbness almost gone, no dr has answer to why it happen?

See neurologist!: You do not say what kind of docs you have seen and what sort of work-up you have had. Have you had a MRI of your brain? Have you seen a neurologist? Please do both, if either have not been done. If you have see a neurologist, and not gotten an answer that is clear to you, please get a second or even a third opinion. Glad this appears to be getting better. Good luck!
