Arachnoiditis is a rare condition that involves inflammation of the arachnoid, which is one of the membranes that surrounds the brain and spinal cord. The inflammation can cause scarring and adhesions that can lead to nerve damage, chronic pain, and other neurological problems. Arachnoiditis can be caused by a variety of factors, including infections, surgery, spinal injuries, and the use of certain medications or diagnostic tests involving the injection of contrast dyes.
Symptoms of arachnoiditis can vary but may include chronic pain, numbness or tingling in the legs, weakness or cramping in the legs, and bladder or bowel dysfunction. In severe cases, arachnoiditis can lead to paralysis and disability.
Treatment for arachnoiditis focuses on managing symptoms and preventing further nerve damage. This may include pain medications, nerve blocks, physical therapy, and surgical interventions to remove scar tissue or relieve pressure on nerves. In some cases, treatment may also involve addressing the underlying cause of the inflammation.
