Complex regional pain syndrome is a chronic and progressive condition that causes pain, skin changes, and in its late stage, muscle atrophy. The Pain Institute of Southern Arizona in Tucson, Oro Valley, or Green Valley, Arizona, has extensive experience relieving the symptoms of complex regional pain syndrome using advanced interventional treatments that target the source of your pain. You can also visit Regional Pain Institute in Apache Junction, San Tan Valley, and Gilbert, Arizona, a division of the Pain Institute of Southern Arizona.

CRPS is a chronic pain disorder that typically affects one limb. There are two types of CRPS. CRPS-I is caused by an injury like a sprain or fracture. CRPS-II develops due to nerve damage. Their characteristic symptom is that the initial pain persists long after the injury or nerve damage heals. Additionally, the chronic pain is disproportionate to the original injury.
Both types of CRPS share the same symptoms. The primary symptom is persistent pain that’s often severe. Your pain begins at the site of your initial injury, which is usually a hand, foot, finger, or toe, then it may spread to include the entire arm or leg.
The affected area may become hypersensitive, making even a slight, gentle touch feel painful. The nerve damage underlying both types of CRPS affects your blood vessels, resulting in changes in your skin color, texture, and temperature.
Most patients also experience:
You may gradually develop muscle symptoms like spasms, atrophy, or loss of coordination.
When your symptoms don’t respond to conventional treatment like medications, the doctors at the Pain Institute of Southern Arizona (PISA) may recommend treatments that stop the nerves from transmitting pain. These are only two examples of their specialized pain treatments:
When any part of your body is injured, sensory nerves carry signals to the spinal cord, and from there to the brain. Clusters of sensory nerves from one part of your body enter your spinal cord at the same spot.
Your doctor can inject a local anesthetic that blocks those nerve signals, stopping them from reaching your brain. As a result, you don’t feel the pain caused by CRPS. Your pain relief typically lasts for several hours after the anesthetic normally wears off, and with additional injections, you may get longer-lasting relief.
A spinal cord stimulator is a medical device that uses a mild electrical signal to block or mask the nerve signals. You’ll have a trial period to be sure it works, then the generator and electrodes are implanted so they can stay in place and provide long-term pain relief.
