Getting feeling and mobility back in my legs, before if i walked or tried to build back muscle, the autoimmune thing would kick in and i would lose even more muscle.. The rituxan would keep that from happening. I get it every 3 months now and they say two years and it should hold with an injection every 6 months. I reported it to the CDC about june of 2021 and they never responded to my report or did anything about it!!
