last Sunday i started getting what feels like charlie horses in my legs. 3 in one leg and 2 in the other. This is friday and I still have them, and a few more appeared. it gets worse when I stand up after sitting even for a few minutes. The other day when i got out of bed, my legs were totally numb above my knees and they couldn't support me so I ended up on my rear end. I was able to stand after a few minutes but they felt weak. I'm still having problems with numbness and weakness and "charlie horses?" Also I'm feeling more unbalanced and dizzy than normal. Does this sound like a relapse or just some odd random thing? also does anyone have any suggestions on how to ease the tightness and weakness?
