Chronic pain can be caused by many different factors. Often conditions that accompany normal aging may affect bones and joints in ways that cause chronic pain. Other common causes are nerve damage and injuries that fail to heal properly.
Some kinds of chronic pain have numerous causes. Back pain, for example, may be caused by a single factor, or any combination of these factors:
Dupuytren's contracture is an abnormal thickening and tightening of the normally elastic tissue beneath the skin of the palm and fingers. This tissue is called fascia. The fascia contains strands of fibers, like cords, that run from the palm upward into the fingers. In Dupuytren's contracture, these cords tighten, or contract, causing the fingers to curl forward. In severe cases, it can lead to crippling hand deformities.
In many cases, however, the source of chronic pain can be a very complex and even mysterious issue to untangle. Although it may begin with an injury or illness, ongoing pain can develop a psychological dimension after the physical problem has healed. This fact alone makes pinning down a single course of treatment tricky, and it is why health care providers often find they have to try a number of different types of curative steps.
