Central sensitization is a condition of the nervous system that is associated with the development and maintenance of chronic pain. When central sensitization occurs, the nervous system goes through a process called wind-up and gets regulated in a persistent state of high reactivity. This persistent, or regulated, state of reactivity lowers the threshold for what causes pain and subsequently comes to maintain pain even after the initial injury might have healed.
What is a chronic pain syndrome?
Your doctor has told you that you have a chronic pain syndrome. What does it mean?
In most cases, chronic pain starts with an acute injury or illness. If the pain of this injury or illness lasts longer than six months, it’s then considered chronic pain. Sometimes, chronic pain subsequently causes complications. These complications, in turn, can make the pain worse. A chronic pain syndrome is the combination of chronic pain and the secondary complications that are making the original pain worse.
Patients and healthcare providers commonly think of pain as a symptom of an underlying injury or illness. Say, for example, you hurt your low back while lifting. Perhaps, you’ve injured a muscle or ligament, or perhaps it’s an injury to the spine, like a disc bulge or herniation. Either way, you now have pain and the pain is the symptom of the injury. The same might be true for any health condition that causes pain, particularly when it first starts.
