What is Sciatica?
Sciatica refers to the pain caused in the lower back, buttocks and legs due to the pressure on the sciatic nerve. Sciatic nerve is formed by the combination of five spinal nerve roots that exit from the lumbar and sacral vertebrae. The nerve is one of the largest nerves in the body and innervates the buttocks, legs, feet etc. The pain due to sciatica is described as a radiating type of pain. It extends through the areas supplied by the sciatic nerve.
Most commonly, sciatica is known to affect only one side of the body. Medically, sciatica is referred to as Lumbar Radiculopathy. It may also be referred to as compressed or pinched nerve pain. Sciatica is not a disease by itself. It refers to the set of symptoms arising due to the pressure on the sciatic nerve. The pressure on the sciatic nerve is caused by the herniation or degeneration of the vertebrae in the lower spine.
Pregnancy, formation of scar tissue, muscular sprains and fractures of the bone can produce symptoms similar to sciatica. Certain disorders of the piriformis muscle and the sacroiliac joint also produces similar symptoms.
Sciatica as said refers to a set of symptoms arising out of the pressure on the sciatic nerve. The pressure effects may occur due to a variety of reasons. Some of the common causes of sciatica are-
• Herniation of lumbar disc
• Degenerative disc disease of the lower spine
• Formation of bone spurs in the lower spine
• Isthmic spondylolisthesis-This occurs due to the minor stress fractures of the vertebrae The fractures vertebrae may slip over the vertebrae below.
• Lumbar spinal stenosis- In this condition there is a severe narrowing of the spinal canal
Other conditions that can create symptoms similar to sciatica are:
• Pregnancy- there is a shift in the body’s centre of gravity due to weight gain
• Epidural fibrosis— a condition where scar tissue compresses on the spinal nerve
• Spinal tumor
• Infections of the lower back
• Ankylosing spondylitis of the sacro-iliac joints
• Piriformis syndrome- In this condition the piriformis muscles exerts pressure on the nerve
• Sacroiliac joint dysfunction
• Obesity and smoking may increase the risk of developing sciatica
• Pain- The most common symptom of sciatica is pain. The pain is usually constant in nature. It is felt only on one side of the body. It usually originates in the lower back and spreads to the buttock, thigh, leg and feet. The intensity of pain is moderate to severe. Certain persons may feel excruciating pain.

Ayurvedic treatment for sciatica:
According to Ayurveda, the ancient Indian system of medicine, sciatica is referred to as gridhrasi. It is so called because the pain experienced due to sciatica makes a person alter his gait to get relief. The gait finally resembles that of a vulture or gridhra in Sanskrit.
According to Ayurveda, all bodily disorders occur due to an imbalance of the three doshas namely vata, pitta and kapha. Sciatica according to Ayurveda occurs due to an aggravation of vata dosha. There might also be an involvement of the kapha dosha also. A build of toxins called ama according to Ayurveda is an important contributing factor. The toxins or ama build up in the body due to an improper digestive mechanism.
The aim of any ayurvedic treatment is to restore the equilibrium of the three doshas. For this Ayurveda takes a holistic approach of treatment. In this approach the body as a whole is subjected to treatment rather than treating the affected parts. It also aims to harmonise the mechanics of body and the mind.
For sciatica Ayurveda prescribes treatments that pacify the vata dosha and brings it back to normal. A specific diet is also prescribed for the patient during treatments.
