2014---I had the 4 doses of Rituxin in 2011 and it stopped the progression of the nerve destruction. My weakness was up to mid calf both legs and finger tips. Now Nothing in fingers and just numbness both feet below ankles. I walk and travel and drive. I see my neurologist every 6 months and as of now no further treatment needed. I would definitely have Rituxan again no matter the cost to be able to walk and write.
