I was diagnosed 8 years ago but it’s just the past couple months I’ve become too week to do almost anything. I have to use a walker now just to get around my house. I almost don’t have the strength to lift my legs to take a step. I’m 66 years old and for the first time I’m getting worried that this might be the way it’s going to be. I’m not sure what to do to try to get my strength back.
