What Is Low Back Pain?

Low back pain is a common, painful condition affecting the lower portion of the spine. It is caused by injury to a muscle (strain) or ligament (sprain). Common causes include improper lifting, poor posture, lack of regular exercise, fracture, ruptured disk, or arthritis. Most low back pain goes away on its own in two to four weeks. Physical therapy and pain relievers can help. A few cases may require surgery.

 

Disk herniation occurs when the soft center of a spinal disk pushes through a crack in the tougher exterior casing.  Some herniated discs cause no symptoms. Others can irritate nearby nerves and result in pain, numbness, or weakness in an arm or leg. Not every disc needs intervention. When needed, treatment includes medication, physical therapy, and possibly surgery.
