Amplified Musculoskeletal Pain Syndrome 

Complex Regional Pain Syndrome in Children

Treatment for children who experience persistent pain, usually following an injury or other physical trauma. 

Complex regional pain syndrome (CRPS) is a condition that involves chronic, excessive pain, usually in one limb (the arm, leg, hand or foot). Also sometimes called reflex sympathetic dystrophy, CRPS is rare, and in most cases, children may develop it after experiencing a trauma or injury, such as fractures, sprains, automobile accidents, limb immobilization/being in a cast, surgery, or small injuries such as bruises and cuts. With CRPS the child continues to experience pain even after the initial injury has healed.

In CRPS, the nervous system responds to an injury in a way that magnifies the effects of the injury. The cause of CRPS may be damage to the central and peripheral nervous systems, but it is unclear why one child may have CRPS after an injury, while another child with the same injury may not have CRPS. It can affect children of any age, though it is seen most often in adolescent girls.


One of the symptoms of CRPS is severe, prolonged pain in the affected limb. It may feel like a burning, shooting or stabbing pain, or a “pins and needles” or squeezing sensation. The pain may start out in the area of the original injury, but may spread to the rest of the limb and may become worse when the child tries to move the limb.

Children with CRPS will often experience increased sensitivity in the affected area, in which normal contact with the skin will feel very painful.

Other symptoms include:

  • Swelling
  • Color changes in the skin of the limb, which may appear blue, red or pale
  • Temperature changes in the limb, which may feel hotter or colder than it usually does
  • Changes in skin texture, which may feel thin or dry
  • Changes in nail or hair growth
  • Joint stiffness
  • Decreased range of motion or abnormal movement in the affected limb


Because CRPS can affect children physically, mentally, and emotionally, our team of experts takes a holistic approach to treat the physical, psychological, and emotional aspects of your child’s condition. Research has shown that early diagnosis and treatment that includes an intensive exercise or rehabilitation program contributes to good outcomes for children and teenagers with CRPS (who generally have better outcomes than adults with CRPS). Depending on your child’s needs, he or she may be cared for by a pain specialist, psychologist, and occupational or physical therapists.

Physical and Occupational Therapy

Physical and occupational therapy focuses on developing an exercise program to keep the painful limb moving to improve blood flow and lessen the circulatory symptoms. Rehabilitation focuses on decreasing nerve sensitivity by teaching the patient techniques to slowly increase muscle use, and pacing their return to activity.

We work with your child on strength, endurance and functional activities to help them return to normal functioning. Rehabilitating the affected limb can help to prevent or reverse the secondary brain changes that are associated with chronic pain, such as nerve hypersensitivity. We work with your child to decrease nerve sensitivity in the affected limb so that normal contact with the skin feels less and less painful.


CRPS can be a painful and disabling condition associated with major changes in lifestyle and mood. Children with CRPS may develop depression, anxiety, or post-traumatic stress disorder, all of which heighten the perception of pain and make rehabilitation efforts more difficult. Our psychologist treats these concerns and teaches your child skills to reduce their fear of pain and help them develop coping strategies to manage pain.


We also focus on weaning your child off pain medicines as appropriate, especially opioids. Decisions to stop or start medications for anxiety or depression are made depending on your child’s individual condition.

Inpatient CRPS Rehabilitation Program

For patients with CRPS whose pain has persisted after attempting outpatient services or other treatments, we provide an inpatient CRPS rehabilitation program. This program is designed to be a brief intensive inpatient program that focuses on returning children with CRPS back to normal functioning. The program consists of a structured daily schedule in which patients see care providers from muliple areas for different aspects of their care and return to functioning. Patients are referred for this program after assessment by the chronic pain management team at Johns Hopkins All Children's.
