What is complex regional pain syndrome?

CRPS is a chronic pain condition that usually affects an arm or leg and develops following surgery, stroke, heart attack, or injury.

It can be a frustrating condition to understand or diagnose since the pain is often more severe than what the original injury caused. Even a mild ankle sprain can trigger CRPS, the symptoms of which continue long after the sprain has healed.

Researchers aren’t sure what causes CRPS, but it’s possibly due to faulty communication between your peripheral and central nervous system. However, other symptoms associated with CRPS indicate it may be linked to an exaggerated inflammatory response to injury.

What are the symptoms of CRPS?

The symptoms of CRPS can vary from one individual to another and may include:

  • Burning or throbbing pain in an arm, leg, hand, or foot and tends to be constant
  • Swelling in the affected area
  • Sensitivity to touch or cold temperatures
  • Skin color changes that may range from excessive paleness to blotchy red or blue
  • Skin in the affected area that is shiny or thin and easily irritated
  • Joint stiffness, swelling, and tenderness
  • Muscle spasms
  • Muscle weakness and tremors

Complications related to untreated CRPS can include muscle loss and atrophy that may eventually interfere with your ability to move the affected limb. You may also develop painful muscle tightening and contractures of the foot and toes or hand and fingers. 

What are the treatments for CRPS?

To relieve your pain and help restore mobility, your provider may recommend:

Sympathetic nerve block

During a sympathetic nerve block, your provider injects anesthesia or numbing agent into a network of nerves called a ganglion. Depending on where your pain is located, your doctor may recommend an injection in the lower back region for leg pain or in the cervical (neck) area for arm pain.

Spinal cord stimulation

A spinal cord stimulator (SCS) uses mild electrical signals to disrupt pain signals traveling from nerves near the spinal cord to the brain. After a trial period to ensure it offers benefit, the small device can be surgically implanted near your spine and adjusted as necessary to provide optimal relief.

Peripheral nerve stimulation (PNS)

Functioning much like a spinal cord stimulator, a PNS is placed over or very near the site of your pain rather than at the spinal cord.

Your provider may also recommend oral steroid medication to reduce inflammation related to CRPS and a course of physical therapy to help improve your strength and flexibility.
