A herniated disc occurs when the soft, gel-like center of a spinal disc pushes out through its outer layer and irritates nearby nerves, which can cause pain, numbness, or tingling that travels into the arms or legs. Physical therapy helps by reducing pressure on the irritated nerve, improving spinal mobility, and strengthening the muscles that support your spine so it can heal and move more efficiently. In many cases, PT can relieve symptoms and help people return to daily activities without the need for surgery.
