Sciatica is pain that originates in the lower hip that moves into the buttock and back of the leg through the sciatic nerve, mostly moving into foot. The pain which starts is often the result of a hurt or inflamed sciatic nerve. The main causes could be an injury, muscular strain, or herniated disc that presses on the nerve.

Symptoms of Sciatica:

The pain of sciatica can occur in different forms - it may start with a cramp in the leg, pain upon sitting, and there may be sensations of numbness, burning, tingling like sensation or it may hurt as "pins-and-needles" pricking along the leg. The pain is most often one-sided. In some cases there may be sharp pain in one part and numbing sensation in other parts of legs. The sensations may extend to the backside of calf and also on the foot sole. Muscle can grow weak either due to pain or pressure on the nerve.

The pain is initially mild in intensity but gets worse over the time; certain activities can initiate the symptoms including;

• 
  Standing or sitting for long periods of time
  
• 
  At night, When you sneeze, cough or laugh
  
• 
  Bending backwards or walking more than a few yards
  

Causes of Sciatica:

These are the longest nerves in human body, extending right from the spinal cord down through the hip and back of leg to the foot. Each of these nerves carry motor signals of sensation of the muscles of the lower leg.

Putting any kind of pressure on the sciatic nerve for long time intervals can lead to the impairment of the nerves. This may happen due to long periods of sitting or standing or due to any accidental damage that might hurt your sciatic nerves and start your troubles.

Treatment

For an effective treatment to sciatica pain, prolotherapy as a medical option could prove to be highly effective and pain relieving. Besides it is also one of the most expensive forms of treatment of pains arising due to sciatica nerve impairment. This procedure involves treating this painful condition through injection of certain chemicals through a saline solution that cause a natural healing effect on the damaged nerves by creating a heating effect around the affected region. The introduction of a foreign substance initiates a spontaneous inflammatory effect in the region. The body sends inflammatory materials to the area affected area, meaning that blood flow is increased.
