A herniated disk of the lumbar spine means the cushioning in a disk that separates vertebral bones of the lower back spine has shifted out of place, according to Mayo Clinic and Healthline. If the jelly-like cushioning in a disk squeezes out, or herniates, pain may occur.
Herniated disks are one of the more common reasons people experience repeated incidents of lower back pain, notes Healthline. While some herniated disks produce severe pain or numbness, others do not produce any symptoms, and individuals are unaware that they have the condition, explains Mayo Clinic. When a herniated disk of the lumbar spine produces pain, individuals usually feel it in the calf, thigh, buttocks and sometimes in the foot. Other symptoms include nerve-related tingling and muscle weakness.
