Arachnoiditis is a chronic pain condition caused by inflammation to a membrane that surrounds and protects nerves of the spinal cord, formally called the arachnoid. Inflammation of the arachnoid can lead to serious health complications such as scar tissue formation around the spinal nerves which can cause them to malfunction in addition to bladder or bowel dysfunction. If the disease is left untreated, symptoms may cause significant disability and prevent individuals from working.
Arachnoiditis may be caused by a number of occurrences or factors, some of which include:
- Forceful or direct injury to the spine
- Bacterial or viral infections
- Prolonged spinal nerve compression
- Complications form minimally invasive or invasive spine surgery
This condition may cause pain, tingling, numbness or weakness in the lower back and legs, muscle cramps or spasms, and unusual sensations such as the feeling of water trickling down the leg or insects crawling on the skin.
