Sciatica

Summary

Sciatica refers to pain caused by the sciatic nerve, which starts at the lower back and runs through the buttock and down the back of each leg. The sensation caused by sciatica can range from mild, sporadic discomfort through to debilitating pain, rendering the sufferer incapacitated and unable to perform day-to-day tasks.

Sciatica is a type of referred pain, meaning that it is the symptom of another underlying condition, such as a slipped disc or an arthritic disease. Nerve entrapment release, Active Release Technique, joint and soft tissue mobilisation and manipulation can be helpful for relieving long-term sciatic pain or discomfort.

The sciatic nerve is the largest nerve in the human body, responsible for delivering motor and sensory functions to the legs and feet. It begins at the lower spine and travels down the back of the legs, where it branches into two at the knee, continuing to the feet.

Sciatica is referred nerve pain as a result of another condition, which places pressure on or irritates the sciatic nerve. In many cases the pain will go away over the course of several weeks, with the aid of pain-killers or anti-inflammatory medication. For more serious conditions, surgery may be required to treat the underlying cause of the sciatica pain. Sufferers who experience a sudden loss of bladder or bowel control, or accelerating weakness in the legs are urged to seek urgent medical advice.

Treatments like nerve entrapment release, Active Release Technique, joint and soft tissue mobilisation and manipulation can generally help to ease the pain of sciatica.

Causes of sciatica

Sciatica is caused by irritation of the sciatic nerve, which can be a symptom of the following:

  • Trauma to the spine
  • Herniated disc (slipped disc)
  • Spinal stenosis
  • Piriformis syndrome
  • Pregnancy
  • Cauda equina syndrome (spinal tumour)
  • Degenerative disc disease
  • Isthmic spondylolisthesis
  • Sacroiliac joint dysfunction
  • Over training
  • Muscular imbalance
  • Trigger points
  • Postural habits

Other symptoms of sciatica

The symptoms of sciatica are generally only felt on one side of the body, although it’s not unheard of for it to felt on both. These symptoms may include:

  • Severe shooting pain down the leg
  • Hot pain in the buttock
  • Aching in the buttock, hamstring and calf
  • Pain in the ankle, foot and toes
  • Increased pain when lifting or straining
  • Increased pain when coughing
  • Lower back pain
  • Tingling or prickling sensations
  • A ‘pins and needles’ sensation
  • Numbness or weakness in the leg
  • Pain which worsens when sitting or standing
  • Relief when lying down

Top tips for sciatic nerve care

  • get plenty of rest (but not too much, as this can worsen symptoms)
  • focus on improving your posture when sitting and standing
  • visit your chemist and find out what over-the-counter medications are available
  • ensure you’re sleeping on a high quality mattress
  • take warm baths to soothe and ease pain
  • practice gentle back exercises
  • invest in ergonomic furniture with lumbar support

Effective treatment of sciatica

For chronic sciatic nerve pain, your doctor may recommend such treatments such as chemonucleolysis (injecting an enzyme into the vertebral disc) or epidural injections. Prescription pain-relief or anti-inflammatory medications may also help to ease the symptoms of sciatica.

Alternatively, physical therapies such as nerve entrapment release, Active Release Technique, joint and soft tissue mobilisation and manipulation may also help sufferers of sciatica.
