Role of Sciatic Nerve

• Movement and function of the lower body relies on the sciatic nerve and the branches of connecting nerves. From the toes to the thighs, the sciatic nerve allows for sensory and motor functions.
  
  

Anatomy of the Nerve

• The sciatic nerve is formed by highly sensitive nerve roots within the spine. Within the spine, the central part of the discs contain proteins that can become inflamed, leading to pain along the sciatic nerve.
  
  

Sciatic Nerve Problems

• The sciatic nerve is the main nerve that is best associated with lower back and leg pain. When vertebrae or disks are inflamed or when they slip, they can compress the sciatic nerve. Pain and numbness can be sporadic, with alternating pain and numbness in different parts of the legs.
  
  

Diagnosis of Sciatica

• A diagnosis of sciatic nerve damage is usually made by X-ray or MRI (magnetic resonance imaging).
  
  

Treatment for Sciatica

• Patients who are suffering a ruptured disc may be treated with bed rest and anti-inflammatory medicine. Physical therapy may also be recommended. In cases where pain can't be controlled with these treatments, the physician may recommend surgery. Depending on the cause of sciatica, surgery can entail either a decompression or removal of the herniated disc.
