I've been on it for 2 plus years now and my walking has gotten progressively worse. No active lesions on my brain or cervical spine so no change in medicine yet. I just had an MRI further down my spine Friday awaiting the results before we discuss changing therapies. But in regards to your question, I get incredibly dizzy and weak prior to my infusion every month. It's very frustrating and honestly I'm hoping they do find some lesions on this latest MRI so we'll have a "reason" why I'm feeling so much worse. I'll keep you posted on what I learn!

Since starting TY, I have also noticed I am suddenly having balance problems. I may be moving too fast, since I am feeling better.

but same thing with one week prior fatigue
