Thank you for becoming members of Prolapsed Discs, the first dedicated social network where people can share their experiences of this excruciatingly painful and debilitating condition. This group has been set up by a fellow sufferer and a post-op (micro-discectomy) survivor who is still in recovery and is passionate about supporting others through this difficult time.

Here you can talk about your condition, the pain you are suffering, your diagnosis, your treatment, the prospect of an operation, how to manage post-operatively or anything else you wish to share with us.

The spine is made up of many bones called vertebrae. These are roughly circular and between each vertebra is a 'disc'. The discs are made of strong 'rubber-like' tissue which allows the spine to be fairly flexible. A disc has a stronger fibrous outer part, and a softer jelly-like middle part called the nucleus pulposus.

When you have a prolapsed disc (commonly called a 'slipped disc'), a disc does not actually 'slip'. What happens is that part of the inner softer part of the disc (the nucleus pulposus) bulges out (herniates) through a weakness in the outer part of the disc. A prolapsed disc is sometimes called a herniated disc. The bulging disc may press on nearby structures such as a nerve (sciatic) coming from the spinal cord. Some inflammation also develops around the prolapsed part of the disc.

Any disc in the spine can prolapse. However, most prolapsed discs occur in the lumbar part of the spine (lower back). The size of the prolapse can vary. As a rule, the larger the prolapse, the more severe the symptoms are likely to be.

Back pain

The pain is often severe, and usually comes on suddenly. The pain is usually eased by lying down flat, and is often made worse if you move your back, cough, or sneeze.

Nerve root pain (usually 'sciatica')

Nerve root pain is pain that occurs because a nerve coming from the spinal cord is pressed on ('trapped') by a prolapsed disc, or is irritated by the inflammation caused by the prolapsed disc. Although the problem is in the back, you feel pain along the course of the nerve in addition to back pain. Therefore, you may feel pain down a leg to the calf or foot. Nerve root pain can range from mild to severe, but it is often worse than the back pain. With a prolapsed disc, the sciatic nerve is the most commonly affected nerve. (The term 'sciatica' means nerve root pain of the sciatic nerve.) The sciatic nerve is a large nerve that is made up from several smaller nerves that come out from the spinal cord in the lower back. It travels deep inside the buttock and down the back of the leg. There is a sciatic nerve for each leg.

Other nerve root symptoms

The irritation or pressure on the nerve next to the spine may also cause pins and needles, numbness or weakness in part of a buttock, leg or foot. The exact site and type of symptoms depends in which nerve is affected.
