Reflex sympathetic dystrophy, also called complex regional pain syndrome or RSD/CRPS for short, is a chronic nerve disorder. Approximately 200,000 to 1.2 million people in the United States are affected by this condition, according to the Reflex Sympathetic Dystrophy Syndrome Association. People who develop any of the symptoms of RSD/CRPS should consult a medical professional for further evaluation and care.
Chronic Pain
As the name of this condition implies, chronic pain is a primary symptom associated with RSD/CRPS. Typically, sensations of pain localize to a body or skin region recently affected by some type of tissue injury or trauma, such as the arm or leg. Pain is often characterized as intense, burning or hot and persists on a continual basis, the National Institute of Neurological Disorders and Stroke reports. Certain psychological factors, such as increased emotional stress, may intensify pain symptoms. These pain sensations typically become worse over time and can be difficult to manage, especially if this condition is not detected early on.
Unusual Skin Changes
People with this nerve disorder often first develop unusual skin changes. The affected skin region may appear discolored and can take on a blotchy white, blue or red hue. The texture of the skin may also change and can become unusually thin or shiny, FamilyDoctor.org explains. People may also notice that the affected skin region is more sensitive to hot or cold temperatures and may be tender to the touch.
Joint Stiffness or Swelling or Muscle Weakness
This nerve disorder can cause abnormal sensations of stiffness, swelling or discomfort in the joints near the affected body region, MayoClinic.com warns. For example, people who develop symptoms of RSD/CRPS in the arm may notice that their elbow or shoulder appears unusually swollen or inflamed and can be difficult to bend, rotate or extend due to excessive joint stiffness. Muscle weakness or unusual muscle spasms may also arise as symptoms of RSD/CRPS, which may cause the affected limb to appear distorted. These symptoms typically become more severe with time.
Limited Mobility
Chronic pain, muscle weakness and joint stiffness can lead to symptoms of reduced or limited mobility in people with RSD/CRPS. Movement difficulties typically only affect the symptomatic body region, NINDS reports. Reduced mobility can significantly impact a person's ability to participate in normal daily activities, such as picking up certain items, standing or walking around without assistance.
Hair or Nail Changes
This condition can result in hair or nail abnormalities in certain people. A person's nails may appear unusually spotted, grooved or brittle, NINDS reports, which may result in easy nail breakage. People may also notice decreased hair growth, which may cause the hair to appear thin or sparse.
