Complications

If CRPS isn't diagnosed and treated early, the disease may progress to more-disabling signs and symptoms. These may include:

• Tissue wasting (atrophy). Your skin, bones and muscles may begin to deteriorate and weaken if you avoid or have trouble moving an arm or a leg because of pain or stiffness.
• Muscle tightening (contracture). You also may experience tightening of your muscles. This may lead to a condition in which your hand and fingers or your foot and toes contract into a fixed position.
