Living with Arachnoiditis

A pain disorder caused by inflammation of a membrane around the spinal nerves.

Understanding Arachnoiditis

Arachnoiditis is a pain disorder caused by inflammation of the arachnoid, one of the membranes that surround and protect the spinal cord nerves.

The inflammation can come from chemical irritation, infection, injury to the spine, long-term pressure on spinal nerves, or spinal surgery or procedures. It may cause scar tissue that makes spinal nerves stick together. It can affect people at any time in life.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Stinging, burning pain in the lower back or legs
  • Numbness and tingling
  • Muscle weakness
  • Joint pain
  • Ringing in the ears (tinnitus)
  • Bladder, bowel, or sexual function changes

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
