What is Sciatica?

Osteopaths regularly treat sciatica with outstanding results. Sciatica is the Latin word for “pain down the back of the leg.” Sciatica is referred pain usually caused by trapping the sciatic nerve in the lower back.

The sciatic nerve runs from the lower back down through the buttocks and along the back of each leg. Sciatica is pain along this nerve and is a relatively a common form of back pain, usually caused by pressure on the sciatic nerve from a herniated or bulging disc.

The pain from sciatica can be anything from infrequent and irritating to severe and debilitating. Usually, it affects only one side, a painful sensation radiating through the buttock and down the leg, and is often associated with a constant ache on one side of the buttocks and leg that may be worse when sitting. A sensation of burning or tingling down the leg, weakness, numbness or difficulty while moving the leg and foot makes it difficult to stand up.

While sciatica can be extremely painful and uncomfortable, it is rare that permanent nerve damage (tissue damage) results from it. Most of the pain is due to inflammation and will improve within a period. Nerve pain is caused by a combination of pressure and inflammation on the nerve root, and treatment is centred on relieving both of these conditions. Typically, sciatica is made worse by bending, lifting, sneezing, and coughing.

Sciatica is a common problem for manual workers, sedentary office workers, and is particularly prevalent during pregnancy.

Causes of Sciatica

The sciatic nerve is the main nerve in the leg and the largest in the body. It runs from the base of the spine, along the back of the thigh to the knee, where it divides into branches. Sciatic pain is usually caused by compression of this nerve root at the point where it leaves the spine. Damage to the nerve can also cause pain.

Among young and early middle-aged adults, the most common cause of sciatica is a prolapsed inter-vertebral disc in the lumbosacral area of the lower back. Among older people, changes in the spine due to conditions such as osteoarthritis may be responsible either by causing localized pressure on the nerve or by narrowing of the spinal canal – called spinal stenosis. Other bone disease or local injury may also be responsible.

Pressure on the sciatic nerve can result from a number of reasons including:

  • Sometimes, just sitting awkwardly can cause sciatica
  • Piriformis syndrome (tightness of the piriformis muscle in the buttock that compresses the sciatic nerve)
  • Spinal misalignments and/or vertebral dysfunction.
  • Herniated disc
  • Poor posture – wearing high heels, prolonged sitting, poor mattress
  • Poor lifting technique and poor bending habits
  • Spinal compressions due to osteoporosis.

Diagnosis of Sciatica

Since there are many disorders that can cause sciatica, your osteopath’s first task is to determine the exact cause of your sciatic nerve interference. The diagnosis is made up of the following procedures:

  • Beginning with a thorough history
  • Spinal, orthopaedic, and neurological examination
  • Special diagnostic imaging investigations such as x-ray, CT, and MRI
  • Posture pro scan may also be required to accurately diagnose your sciatica.

Treatment of Sciatica

Treatments in osteopathy has the following main objectives:

  • Reduce pain
  • Restore movement
  • Strengthen weakened muscles
  • Reduce tension

As sciatica is due to pressure on the sciatic nerve, it stands to reason that treatment involves removing this pressure. Osteopathy treatment aims to achieve this by reducing nerve pressure caused by poorly moving spinal joints as well as easing muscular tension in the lower spine, buttock, and leg.

This is achieved by using a combination of the following techniques:

  • Spinal mobilizations
  • Massage therapy and trigger point therapy
  • Stretching tight muscles, joints, tendons, and ligaments
  • Ultrasound and other electrical stimulation devices
  • Advice in relation to how to minimize pressure and irritation of the sciatic nerve.

In addition to this, you will be given a series of home stretching exercises and will be asked to apply ice and heat to help aid your recovery.

If you are suffering with sciatica at the moment please do not delay. You can achieve the best results when you address the symptoms early.
