I am having pain in my back across the hip area, about where the spine ends. This is causing pain in my leg also. The pain will get somewhat better when I am up moving around at a normal pace such as walking, but if I use stairs or make small steps(such as around a kitchen) the pain can get very intense. When I am trying to sleep, it also hurts to turn over, I have also experienced muscle quivering in my thighs. One night I stretched my legs to relieve the pain and my left left started jerking, the pain is also worse in my left leg.
