Complex Regional Pain Syndrome


Complex regional pain syndrome (CRPS) is a painful condition that can occur in one or more of your limbs. CRPS has 2 types. Type 1 has no known cause. Type 2 is caused by nerve damage.


Follow up with your healthcare provider or pain specialist as directed:

You may need to have weekly visits with your healthcare provider or pain specialist to see if your treatment is working. Bring a list of any questions you have so you remember to ask them during your visits.


  • Medicines may be given to treat swelling, nerve pain, or blood flow. You may need more than one medicine to treat your symptoms.
  • Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Physical therapy:

A physical therapist can teach you exercises to help improve movement and strength of your injured limb.

Manage CRPS:

  • Stay active. Movement of the injured limb may help lower your pain.
  • Find ways to relax. Your pain may increase when you are anxious. Ask your healthcare provider about relaxation techniques that help lower pain.

Contact your healthcare provider if:

  • You have limb pain that you think is worse than any recent injury should cause.
  • You have limb pain that continues after an injury heals.
  • You have limb pain caused by things that do not normally cause pain, such as a touch to the skin.
  • You have swelling, sweating, and skin temperature changes in an injured limb.
  • You have trouble moving an injured limb.
