Thanks everyone for your responses. I appreciate the info.
Well, I have 1 doctor saying yes, MS--and one doctor saying not enough symptoms to diagnose MS. I, of course, prefer the latter!
I have a lot of trouble describing whats going on w/my legs. Seems like there's no exact words for it. My knees don't give out. It started from the knees down and is now the whole leg and butt/lower back (--probably sore because of the way I'm walking). It's not even that I can say they feel heavy, like jello, or like walking through mud. They are painful but it's not nerve, muscle, or sharp pain. More like weakness, like maybe I've walked 20 miles, and they're really tired. Feet hurt too. Stairs are a killer. Before this started I could shop for hours, walk all over the store--now when I leave the supermarket I'm hanging on the basket, walking real slow, exhausted, like I dread another step. It stinks. I have a real problem with not being able to do things like I always have. Very upsetting.
I'm so glad there is this site where others know what you're going through, and can help and be supportive. I guess I'll be sticking around for a while, as I really have no other support whatsoever.
