Reflex Sympathetic Dystrophy, now known as Complex Regional Pain Syndrome Type I or CRPS-I, is a rare condition that affects a significant majority of CRPS cases, accounting for approximately 90%. This condition is characterized by excruciating pain that is out of proportion to any external stimulus. Unlike other forms of CRPS, Reflex Sympathetic Dystrophy occurs even in the absence of nerve damage.
Pain
CRPS and reflex sympathetic dystrophy are characterized by intense pain originating from within the limbs. Patients often describe this pain as a sharp, tearing, or burning sensation. Even a gentle touch on the skin can trigger excruciating pain in individuals with reflex sympathetic dystrophy. In some cases, patients may also experience complete sensory loss. Many accounts report a gradual progression towards numbness.
Other Symptoms
Aside from experiencing pain and sensory changes, there are several additional symptoms that may manifest in individuals with reflex sympathetic dystrophy. One common symptom is the development of red, warm, and swollen limbs. As the condition progresses, the skin may become colder and exhibit a dark or blue color. Regardless of the skin’s color or temperature, swelling is typically present. In some cases, the skin may become thin and shiny. Furthermore, reflex sympathetic dystrophy can also impact nail and hair growth in the vicinity of the affected area.
