What Causes a Herniated Disc and How Can It Impact Your Back and Legs?

Herniated discs, often referred to as slipped or bulging discs, are a prevalent condition, especially in the lumbar spine area of individuals around middle age. Despite their name and location, the symptoms these discs produce can sometimes be unexpected.

According to HSS spine surgeon James E. Dowdell III, MD, a herniated disc in the lower back is more inclined to affect the buttocks, legs, and feet rather than the back itself. The disc herniates due to a tear in its robust outer layer, known as the annulus fibrosus. This tear allows the gelatinous inner section, termed the nucleus pulposus, to seep out.

If this herniation occurs lower in the back, it may irritate the sciatic nerve. This irritation can lead to pain that radiates from the buttock down through the leg. Interestingly, as noted by Harvard Health, about 90% of the pain caused by herniated discs dissipates on its own within six months.

A herniated disc can occur not just in the lower back but also in the neck. Spine specialists Jacob Buchowski, MD, MS, and Deeptee Jain, MD have discussed the prevalent symptoms of a herniated disc and the variety of treatments available to alleviate the associated pain. Typical symptoms can include arm or leg pain, numbness, or tingling, contingent on the disc’s location.

For many, a herniated disc might be a familiar term, but it is crucial to understand that it’s not the only condition causing back pain. Conditions like spondylolisthesis can also lead to recurrent back pain, emphasizing the importance of getting a precise diagnosis for any spine-related issue.
