- See "Herniated Disc". When a herniated disc occurs in the lower back, pressure is put on the Sciatic nerve which runs down the leg to the foot. Pressure to this nerve causes pain running down the buttock and leg. Pain may worsen when sitting for prolonged periods of time, bending and lifting objects. Numbness, tingling and weakness that radiates down to the foot may also be felt.
Physical therapy will work to ease the pain, stretch the back out and strengthen the back muscles to prevent further damage.
