Pain Condition --- Sciatica (Leg Pain)


Radiating pain from back or buttocks into the leg is called Sciatica. It can involve buttock and thigh or it can go down all the way to the ankle and toes. It is due to the compression of the nerve root (pinched nerve) in the spinal area. When nerve root gets compressed (pinched), it gets irritated and causes radiating pain down the leg. The nerve root gets compressed by a bulging or herniated intervertebral disc (Intervertebral disc is a jelly donut like structure between the vertebral bones, which acts like a cushion or shock absorber. Herniated disc is a condition when the jelly like interior comes out of the disc. It has chemical irritants, which irritate the nerve root.). The nerve root can also be compressed by arthritis or bone spur formation from facet joints. Another common cause for sciatica is Spinal Stenosis. Spinal Stenosis is a condition where the spinal canal or the neural foramina (holes in the spine, between the bones, through which the nerve root comes out of the spine) gets narrow due to a variety of causes like disc bulge, facet arthritis, malalignment of vertebrae (Spondylolisthesis), etc.

Interventional treatment of Sciatica includes Epidural Steroid Injection or Selective Nerve Root Block (Transforaminal injection). If injections do not work, then minimally invasive procedures like Disc Decompression (Nucleoplasty) can be considered.
