Prolapsed Disc ● Slipped Disc
A herniated or prolapsed disc can cause severe back pain and sciatica.
Between the Vertebra there are the flat, plate like Discs. These Intra-vertebral Discs are what allow spinal movement to take place. If a Disc packs up - So do we!
The disc is formed of two parts, and outer elastic fibrocartilage and an inner deformable nucleus, basically you have a squidgy ball contained within a firm, elastic mesh. The squidgy ball moves/deforms in regard to movement and other loads.
When a Disc Bulges through the fibrocartilage - a Prolapsed Disc - the bulge will often press on a nerve. This can be disabling, and when serious may require Surgery.
With an uncomplicated Prolapsed Disc in the Lower Back it is worth trying a series of back extension exercises as soon as you possibly can. Doing these exercises will, hopefully, give the disc bulge enough space to be absorbed back into the disc. Recent research suggests this is the best approach.
These exercises can be quite uncomfortable to do, the back pain may become worse, but any pain radiating to leg, buttock or thigh should settle. This is because the pressure is being taken off the nerve - the serious part of the injury. The back pain is due to the inflammation around the damaged disc and the associated muscle spasm in the muscles that are splinting the spine.
When the Disc Prolapse is in the Neck - the Cervical Spine - there are similar exercises that should also be followed.
At this Acute Stage it is NOT a wise idea to use Spinal Manipulation - as this may make the condition worse. In time, when the inflammation around the Disc and Facet Joints has settled, Spinal Manipulation can safely be used to aid recovery.
There are certain important criteria with Prolapsed Discs. A Disc Bulge will often cause Pain and Paraesthesia (Numbness or Pins and Needles). But in more serious cases the Pain may be intractable, there may be limb weakness, "electrical" sensations and possible loss of Bowel and/or Bladder Control - Cauda Equina Syndrome - loss of sensation in the area that would be in contact with a bicycle saddle if you were sitting on it - This is Serious and requires immediate Medical Attention - Go to Accident & Emergency as soon as you can.
The majority of "Slipped Discs' will settle down over three months. An Intervertebral Disk does not have a blood supply, it absorbs fluid from the vertebra above and below. This usually happens at night when there is less pressure on the disc, a person can be up to 3 cm taller at the start of the day. This may help explain why a disc injury takes such a long time to completely heal.
Astronauts in space, who are not subjected to the force of gravity, are also taller when they return to Earth because of fluid absorption into the disc.
Statistics show that the majority of disc prolapses occur between the ages of 30 and 50, the median age being 40. This is because the degenerative process is not so pronounced in younger people, and in older people the elasticity of the disk is decreased to such an extent that the disc cannot actually bulge. The older population has to contend with conditions such as arthritis and spinal stenosis.
Smoking is also an issue with this disease, a study showed that after two hours of exposure to cigarette smoke metabolism within the disc was decreased by 50%.
