Hi @patirl – thank you for your message. If you don’t mind me asking, do you feel tysabri helped your symptoms while you were using it? I guess everybody experiences different symptoms but I’m desperate for a treatment which will help me recover from my existing symptoms which are becoming quite problematic in my daily life. After 3-4 minutes of walking, sometimes less, my legs just struggle to walk/lift/bend and I end up dragging my feet. Praying for a miracle treatment!
