If you run your fingers down my spine you can feel a bulge right about the L1 vertebrae. I was playing volleyball friday and by the time I was done, my back was in severe pain. I had dropped to the floor to get a ball and it felt like my spine compressed in the areas of the bulge. From that instance forward, I had pain when I would bend forward with a slight arched back (to bump the volleyball), bend my torso to the left side, or getting out of the car. I would also get some pretty good bouts of pain from just sitting. Just walking would hurt if my torso swayed off center. When I slept that night, I was woken up by the pain, especially if I went to turn from back to stomach. The pain has gradually decreased since saturday to where I have full range of movement. The bulge has been there for a long time. It didn't just appear. Also, I don't have numbness in any extremities. Periodically, in times of high stress I get pain in my sacrum region. Any ideas?
