Spinal disc herniation is a medical condition affecting the spine in which a tear in the outer fibrous ring of an intervertebral disc allows the soft central portion to bulge out beyond the damaged outer rings. Disc herniation is usually due to age-related degeneration although trauma, lifting injuries, and/or straining have also been implicated.
If there is lumbar disc damage, back pain radiates into the buttock and below the knee. In cervical disc damage, neck pain radiates into the arms and hands.
Treatments for herniated discs can include transforaminal epidural steroid injections, epidural steroid injections and intrathecal pain pumps.
