After a while, pain wears a person down, draining their energy and sapping their motivation. They sometimes attempt to limit social contact in an effort to reduce stress and to decrease the amount of energy they have to spend reacting to their environment. Eventually, many people with chronic pain develop depression-like symptoms: lack of interpersonal interaction, difficulty concentrating on simple tasks, and the desire to simplify their life as much as possible, which often manifests as seeking isolation and quiet. Sleeping often makes the pain less intrusive, and that combined with the exhaustion that pain induces means that it isn’t uncommon for a person to start sleeping upwards of ten hours a day.

Some recent studies have also shown that chronic pain can actually affect a person’s brain chemistry and even change the wiring of the nervous system. Cells in the spinal cord and brain of a person with chronic pain, especially in the section of the brain that processes emotion, deteriorate more quickly than normal, exacerbating many of the depression-like symptoms. It becomes physically more difficult for people with chronic pain to process multiple things at once and react to ongoing changes in their environment, limiting their ability to focus even more. Sleep also becomes difficult, because the section of the brain that regulates sense-data also regulates the sleep cycle. This regulator becomes smaller from reacting to the pain, making falling asleep more difficult for people with chronic pain.
