What is arachnoiditis?
Arachnoiditis describes inflammation which occurs inside the spine, around the spinal cord and spinal nerve roots.
What causes arachnoiditis?
Arachnoiditis can develop after back injury, spinal surgery, infections such as meningitis, and sometimes after injections into the spine. Pain comes from nerve roots and generally impacts the lower parts of the body, but can affect the spine in the head, neck and upper back. Damaged nerve roots can cause muscle spasms and jerks, and weakness of muscles.

changes in vision
joint or muscle pain
unusual sensations, such as burning or tingling
ringing in the ears
