- This injury is also called a "slipped" disc. A disk herniates when it's nucleus, a jelly-like substance in the center meant for shock absorption, pushes against the outer part of the disk. In some cases, when the disk is worn with age or wear, the nucleus can push all the way through and it puts pressure on the spinal nerves, causing pain. Lifting, pulling, bending, or twisting the wrong way can cause this injury. Symptoms include back pain, especially when bending or lifting, and the pain may extend to the hip or buttock area.
Physical therapy will utilize modalities such as heat, electrostimulation, and massage to ease pain. Stretching, weight lifting and various exercises will also be completed to strengthen the back overall.
