A herniated disc is the projection of a portion of a disc between two vertebrae. The hernia may be responsible for the compression of a nerve passing nearby as well as pain along the nerve: as is the case with sciatica. After diagnosis through medical imaging, such as a CT scan or MRI, medical treatment is conducted. In case of persistent pain, surgery may be considered. Microsurgery is a possibility, which aims to remove the hernia and release the nerve root. This operation is performed under general anesthesia, with the patient staying in the hospital for a few days; the results are satisfactory despite the persistence of some pain and complications are rare.
