Disk injuries in the spine, usually known as slipped or herniated disks, occur when the jelly-like inner core of a disk leaks through the outer part of the disk, according to Spine-health.

Sometimes a herniated disk causes no symptoms, notes Mayo Clinic. Often, though, the herniated disk puts pressure on the nerves around it, which can cause pain to radiate into the legs where the affected nerves run. This nerve pain, known as sciatica, is sometimes accompanied by a sensation of weakness or numbness. Coughing, sneezing or certain movements of the spine may exacerbate sciatica.
