Sciatica is a set of symptoms including pain and strange sensations in the low back, buttock and leg. Sciatica can be caused by compression or irritation of one of the spinal nerves in the low back. This may be due to a lumbar disc herniation or prolapse. Another cause is tightness in the piriformis muscle (a deep muscle in the buttock) - sometimes aggravated if you sit with a wallet or keys in your back pocket. Rarely, the cause of sciatica stems from a growth in the spinal canal, in which case you may need surgical intervention.
In addition to pain, which is sometimes severe, there may be numbness, muscular weakness, "pins and needles" or tingling and difficulty in moving or putting weight through the leg. Typically, the symptoms are only felt on one side of the body.
Treatment for sciatica will depend upon the underlying cause of the symptoms. Manipulation and stretching (traction) may help to resolve the problem, but it can take several weeks for all symptoms to subside. Some people with disc problems have recurring episodes of sciatica throughout their life. Although Osteopathy may help with the short-term symptoms, you may be advised to strengthen the deep abdominal muscles (to support the lumbar spine) - Pilates exercises may be of benefit here (for a list of Pilates teachers in the area, click here).
The term 'slipped disc' doesn't give a realistic explanation of what has happened in your spine to cause pain and other symptoms.
The disc between two bones in the spine contains two parts - a tough, fibrous outer ring, and a thick fluid material in the middle, which provides a cushion between the bones.
Twisting injuries can cause the outer disc fibres to tear and cause pain over that area of the back and possibly also in a predictable pattern down the back to the leg.
When the inner disc material pushes through the outer fibrous ring, due to degeneration of the disc, or through an injury (e.g. lifting a heavy load), this can either push on the nerves passing between the bones of the spine, or can just cause a chemical irritation which produces pain and other symptoms in the body along the path of the nerve.
For example, at the base of the spine (the weakest point), the disc could push out and irritate the nerves at the base of the spine, causing a referred pain pattern into the leg and buttock on that side, with weakness in the leg.
The BackCare charity (www.backcare.org.uk) reports that almost half the adult population of the UK suffers from low back pain at some point during the year.
The following factors could contribute to back pain:
In 2000 the National Health Service spent over £1 billion on back pain related costs. In the private healthcare sector £565 million is spent on back pain every year.
The Health and Safety Executive estimated (in 1997) that musculoskeletal disorders, which include back pain, cost UK employers approximately £600 million per year.
The Department of Health in 1999 recorded that nearly 40% of back pain sufferers consulted their GP for help and 10% visited a practitioner of complementary medicine (osteopaths, chiropractors and acupuncturists).
When experiencing back pain it is very important to stay active. Bed rest will only make the pain worse. Physical exercise can be a very effective method to reduce the pain and discomfort that long-term pain sufferers experience.
Trouble with your back does not simply produce pain in the back. Often it may cause symptoms in more remote areas such as the buttocks, groin, hips and legs (commonly called sciatica). Problems in the spine and neck can also cause symptoms such as dizziness, headaches, clicking jaw, pins and needles and many more.
Indeed, research has shown that problems related to the back may affect over 60% of the UK's population at some stage in their lives.
Osteopaths are trained professionals who are skilled in diagnosing problems, including those which may require further investigation if necessary. Osteopaths have treated many hundreds of thousands of patients successfully over the past one hundred years and continued success is demonstrated by reliable and practical results.
The osteopath will explain to you clearly what the problem is. If they can help they will explain what they can do to help and also offer advice on self-help treatments.
When young, the body can adapt easily to the stress and strain it is put under. As it grows older (over 25 years!) it begins to lose some of the elasticity which gives the body the flexibility to cope and adapt.
In particular this applies to the discs between the vertebrae and the joint cartilage. These require regular movement to ensure their maximum range and thereby increase local circulation and nutrition to the surrounding fluids and tissues.
