I was sitting and leaned forward and I felt a twing in my left lower back , buttocks area then my back went into spasms and I couldn't move. I was laying on my kitchen floor for three hours before I could move without going into spasms again. I'm still in pain and have sever pain when I move. It is all on the left lower back hip area. It aches when I'm not moving and sharp pains when I do move
