  • injury, the effects of intramuscular injection;
  • herniated disc hernia of the IPOA;
  • hypothermia
  • posture;
  • infection and toxic effects of certain substances;
  • diabetes.

The Most common causes of pain along the sciatic nerve is degenerative disease of spine (osteochondrosis, spondylosis, spondylolisthesis, osteoarthritis of spine joints etc.). In this case, the called vertebrogenic sciatica. On the second place by frequency of occurrence are tunnel neuropathy piriformis syndrome, etc. It is about these pathologies usually mean when they say “a stiff sciatic nerve”.

  2. Magnetic resonance imaging. It can help to identify the offset of the discs, herniation, or entrapment.
  3. CT scan of the spine. Required if a complete picture of the disease is not identified when performing magnetic resonance investigations and need more data that will help to correct treatment.
  4. x-ray examination.
  5. examination of the cerebrospinal fluid by indications (suspected viral or bacterial lesion of the nerve roots).

Treatment inflammation
