Complications to the network of nerves along the spine affect every aspect of our lives. Annually, there are at least 25,000 cases of arachnoiditis, and the causes range from infection complications to surgery. This neurologic pain condition is complex, and research is still ongoing. What experts do know is that when it comes to spinal pain management, it is essential to ensure people with the condition receive enough information and relief to live as comfortably as possible.


1. What Is Arachnoiditis?

The meninges are protective cerebrospinal membranes. The membrane between the innermost layer, the pia mater, and the outermost layer, the dura mater, is often called the arachnoid mater. Arachnoiditis is painful inflammation of this layer. Collagen forms between the pia and arachnoid layers, and the resulting fusion of the nerve roots interferes with blood supply, resulting in atrophy. This can happen at any location along the spine, though the chronic form of arachnoiditis once occured most often in the upper spine. Since the 1950’s, however, doctors have noted arachnoiditis is more common in the lumbar spine.
