Complex regional pain syndrome (also known as RSD) is characterized by pain that is greater than would be expected from the injury that causes it. RSD normally affects an arm or leg. Complex regional pain syndrome typically develops after an injury, surgery, stroke or heart attack, but the pain is out of proportion to the severity of the initial injury.
Symptoms may change over time and vary from person to person. Most commonly, pain, swelling, redness, noticeable changes in temperature and hypersensitivity (particularly to cold and touch) occur first.
Over time, the affected limb can become cold and pale and undergo skin and nail changes as well as muscle spasms and tightening. Once these changes occur, the condition is often irreversible.
Complex regional pain syndrome occasionally may spread from its source to elsewhere in your body, such as the opposite limb. The pain may be worsened by emotional stress.
In some people, signs and symptoms of complex regional pain syndrome go away on their own. In others, signs and symptoms may persist for months to years. Treatment is likely to be most effective when started early in the course of the illness.
If you experience constant, severe pain that affects a limb and makes touching or moving that limb seem intolerable, see your doctor to determine the cause. It’s important to treat complex regional pain syndrome early.
Treatments for Complex Regional Pain Syndrome vary, but here are some treatments below:
The key is to seek treatment from a specialist and obtain a primary diagnosis. Conservative treatments may include simple rest and activity modification. Pain management through medication may help as well. Physical therapy and surgery maybe also be considered.
