Hello, I am a 53 year old male that was diagnosed in 2012 with rrms and is now in a progressive stage. I was on copaxone for 2 years rebif for 1 year and currently on retuxin every 6 months. I have tried every thing to slow the progression but have not found anything to slow it (i.e. diet,exercise,drugs,herbal). My walking has gotten a lot worse even when I keep pushing myself hard. Has anyone found something that helps with walking? I am on ampyra.
