Hi ya, I'm new to this group. I was diagnosed in 2010. Fortunately I have not had any relapses, well not that I know of. But recently my leg muscle above my knee has felt like I've done a really hard work out but I haven't, and is feeling pretty weak and wobbly, could this be the MS? Or just arthritis? Thanks, I know it sounds simple and I'm not as bad as some of you on this site. My heart goes out to you!! X
