In sure cases, a tumor may additionally compress the nerve, and other conditions consisting of diabetes might purpose it to be damaged.

A herniated disc inside the lumbar vicinity is accountable for maximum of the cases of sciatica. Typically, a herniated disc compresses one or greater of the spinal nerve roots which are answerable for the formation of the sciatic nerve. A herniated lumbar disc in one among two ways reasons sciatica:

  • Direct compression: It is possible for a lumbar disc to bulge or for the soft inner material of the disc to seep out or herniate through the fibrous outer core and push on the sciatic nerve.
  • Chemical inflammation: It is possible that an acidic chemical irritant from the disc will seep out and cause inflammation and irritation in the region around the sciatic nerve.

A herniated disc may compress the sciatic nerve on one side, resulting in symptoms in just one leg, or the disc may bulge or herniation from both sides, resulting in symptoms in both legs and lower back pain.

Another cause is degeneration. The sciatic nerve may be compressed or irritated because of the degeneration of tissues in the lumbar spine. It may cause the synovial tissue in the joint’s capsule to become inflamed and swollen, which can lead to further joint degeneration.

Furthermore, the doctor may do specialized clinical tests to establish whether the patient is experiencing sciatic nerve pain. These tests for sciatica include “Slump test and Straight leg raise (SLR) test.”

Imaging tests like MRI and CT-scans are also performed in order to establish sciatica diagnosis.


Physical therapy, medicines, therapeutic injections, as well as alternative therapies are generally used as first-line treatments for sciatica. Nonsurgical therapy for acute sciatica typically takes 4 to 6 weeks.
