Complex Regional Pain Syndrome in San Marcos, TX

What Is Complex Regional Pain Syndrome?

Complex regional pain syndrome (CRPS) is a chronic pain condition characterized by prolonged pain in one or more limbs that is disproportionate in intensity or duration to the original injury or event that triggered it. The condition most commonly affects an arm, hand, leg, or foot, and the pain it produces can be persistent and difficult to manage without appropriate intervention.

CRPS is sometimes referred to by an older term, reflex sympathetic dystrophy syndrome (also called reflex sympathetic dystrophy), particularly when discussing earlier literature or certain insurance classifications. Regardless of terminology, the condition involves dysfunction in the peripheral nervous system and, in some cases, the central nervous system, which together regulate how pain signals are processed and perceived. Pain management specialists recognize two forms of CRPS, distinguished primarily by whether a specific nerve injury has been identified.

Because CRPS is a complex regional pain syndrome that can evolve over time, early evaluation by qualified pain specialists is important. The pain management team at Greater Austin Pain Center in San Marcos, TX is experienced in evaluating and treating this condition using a multidisciplinary approach.

How Complex Regional Pain Syndrome Affects the Body

CRPS can present as either an acute or chronic pain condition. In some patients, symptoms may resolve with short-term treatment; in others, the condition becomes a long-term source of significant pain and functional limitation. The pain associated with CRPS is not simply discomfort at the site of an old injury. It typically involves changes across the affected limb and, in severe cases, can spread to other areas of the body.

Common symptoms of complex regional pain syndrome include:

• Continuous burning or severe pain in the affected limb
• Swelling of the affected area
• Sensitivity to light touch or temperature changes in the affected area
• Changes in skin color (the limb may appear red, pale, or bluish)
• Changes in skin temperature in the affected area
• Altered hair or nail growth on the affected limb
• Limited range of motion
• Muscle weakness or, in advanced stages, muscle loss

In later stages, the affected limb may experience more significant changes in skin color, texture, and strength. Severe cases of complex regional pain syndrome have been associated with long-term disability when the condition goes untreated or is not adequately managed. Pain symptoms can also, in some cases, involve adjacent areas such as the neck, joints, or even spread to the opposite limb.
