I don't consider that a long time in MS counting.
As one example I used IVIg for years and was delighted that after several months I regained sensation and use of my right foot. It had been dead for two years and supposedly hopeless. Never give up, never surrender! Sorry, I just watched Galaxy Quest last night, but it remains a good motto.
edit -- in a very bad period several years ago I asked people to post their positive stories to give me hope. I received an outpouring of amazing things that people had experienced. This disease is unpredictable in every way. As long as we're alive good things can happen. Hang in there and take care of your basic health.
