I think I may be going into an MS flare for the first time since my initial attack in 2000.  It could just be muscle fatigue because on Sunday at the grocery store I was looking at an item that was on a bottom shelf, and I went from a floor-level squat to standing without holding onto anything.  At the time it seemed like it required quite a bit of effort to thrust myself upwards, and I don't usually squat anyway because of my cranky left knee, so I could have just overworked my leg muscles.  Since yesterday my legs have felt a little bit weak, especially the left, and my gait is a little off, and this afternoon my legs feel a tad heavy.  I think I may have mentioned in an earlier post that recently my restless legs have been occurring during the daytime as well as at night, sort of like painless spasms if I'm sitting for long periods of time.  I hadn't paid much attention to that, but the stuff over the last couple of days is freaking me out.  I called my neurologist and explained the situation, including the move at the grocery store, and he said to give it a couple of days and if it doesn't get better, he'll work me in.  I'm hoping that it's just muscle strain and that my lack of interferon injections over the last several months isn't coming back to bite me in the butt, because I so cannot afford to start back on them right now...
