I was having severe hip & leg pain, and lower back pain for about a week...to the point I had to use my cane to walk. These were shooting pains, and I couldn't sit, lie down, walk or stand for more than a couple of minutes. I went to my Chiropractor and he said I had a pinched nerve. My pelvis was out of place!! I have no idea how that happened. He asked me if I slipped or fell or lifted anything heavy (I can't lift anything heavier than a gallon of milk and sometimes not even that). So, he put me back into place and said no vaccuming for at least this week. He also said if I can keep from it, that I should not sleep on my stomache.....well, I've been a dtomach sleeper from the time I was born, so it's hard to change now. But, I am trying. I am still in pain and have sharp pain in my hip and leg.....my knee is effected by this too. I suppose I'll have to go back again, but at least the pain is about 50% better....for now.
