Survey Description

The purpose of this survey is to gather opinions from patients diagnosed with a so called Complex Regional Pain Syndrome (CRPS), also known as: Reflex Sympathetic Dystrophy (RSD), Causalgia, Algodystrophy, Algoneurodystrophy, Sudeck's Atrophy, Shoulder-Hand Syndrome, Reflex Neurovascular Dystrophy, Fracture Disease, Morbus Sudeck, M. Sudeck.

CRPS is a chronic pain condition most often affecting one of the limbs (arms, legs, hands, or feet), usually after an injury or trauma to that limb. CRPS is characterized by prolonged or excessive pain and other signs, indicating autonomic and inflammatory changes in the region of pain, like:

• obvious changes to skin color,
• skin temperature,
• sweating relative to the unaffected side,
• altered patterns of hair, skin, or nail growth in the affected region,
• reduced strength,
• edema and/or swelling in the affected area.

In its most severe form, patients present with a limb displaying an extreme sensitivity to pain as well as normally non-painful stimuli such as touch and cold are experienced as painful.
