Kyle has given you some good advice, and I'd ask my neurologist before going on b12, your levels may be adequate as they are.

Hi Mahroz - Welcome to the group.
If you've experienced muscle spasms in your neck and had your left leg go numb, you have had symtoms :-)
Sadly there is no cure for MS. Many of us with MS have low b12 levels and take supplements. I cannot advise for or against taking b12. This is a conversation you should have with your doctor.
