Disc problems of in the lumbar spine are more common than the cervical spine, with disc issues in the thoracic spine being more rare.
When a lumbar disc bulges and puts pressure on part of the sciatic nerve then symptoms such as numbness, pain, and tingling can occur any where from the back to the foot. Symptoms down the leg are often referred to as sciatica, and about 90% of cases of sciatica are caused by trauma to one or more of the lumbar intervertebral discs.
The most common level for this to occur is between the 5th lumbar vertebra and the sacrum.
Treatment incorporates the whole of the spine and the pelvis, and not just one segment. By ensuring correct alignment and normal function of all other areas the amount of work that the lower back has to do is minimized. Often kinesiotape is used to support the area but maintain a functional range of movement, while a specific program of core exercises and kinetic chain work is given. This allows the body to regain its efficiency of movement and minimizes the chances of any future disc issues.
