Complex Regional Pain Syndrome
Symptoms and Treatment
Complex regional pain syndrome (CRPS) is a chronic pain condition that usually affects one limb, such as an arm, hand, leg or foot. It is characterized by persistent pain that may be more intense than expected after an injury or medical procedure.
In addition to pain, it may cause changes in skin temperature and color, swelling, extreme sensitivity and difficulty moving the affected area. Recognizing these symptoms and seeking medical evaluation can help patients receive timely care.
What is complex regional pain syndrome?
Complex regional pain syndrome is a disorder involving the way the nervous system processes pain. It may develop after an injury, fracture, surgery or another event affecting a limb. In some cases, the triggering event is not clearly identified.
It has also been referred to by historical names such as reflex sympathetic dystrophy and causalgia. These terms are associated with the two main types of the condition.
The severity of the pain does not always correspond to the extent of the initial injury. Even light touch or a change in temperature may cause significant discomfort in some people.
What causes complex regional pain syndrome?
The exact cause of complex regional pain syndrome is not fully understood. It may involve an abnormal response of the nervous system and other mechanisms involved in pain regulation after an injury.
Events that may occur before the condition develops include:
What are the symptoms of complex regional pain syndrome?
Symptoms usually affect the involved limb and may change over time. Their severity and combination vary from person to person.
Common symptoms include:
How is complex regional pain syndrome diagnosed?
Diagnosis is primarily based on medical history and a physical examination. The healthcare professional reviews the characteristics of the pain, any history of injury or surgery, and changes affecting the limb.
The examination may include an assessment of sensitivity, skin temperature and color, swelling, sweating and mobility.
There is no single test that confirms this condition. Depending on the individual case, additional tests may be requested to rule out other conditions or provide supporting information, including:
What is the treatment for complex regional pain syndrome?
Treatment is tailored to the symptoms, their severity, how long they have been present and each person's needs. It generally aims to relieve pain, maintain or restore movement, and support everyday activities.
Physical rehabilitation and occupational therapy
Rehabilitation is an important part of treatment. Physical therapy and occupational therapy may help maintain mobility, restore limb function and reduce limitations in daily activities.
The program should be gradual and individualized to avoid excessively increasing pain. In some cases, desensitization techniques, motor imagery exercises or mirror therapy may be considered.
Medication and pain management
A healthcare professional may consider medication to manage pain and other symptoms, depending on the individual case. Options may include certain pain relievers, medications used for neuropathic pain and, in specific situations, corticosteroids.
When pain is persistent or difficult to manage, a specialist evaluation may be needed to consider other options, such as nerve blocks or neuromodulation techniques. These procedures are not appropriate for everyone.
Psychological support and other options
Living with persistent pain can affect sleep, mood and daily activities. Psychological support may help patients develop strategies to cope with pain and remain engaged in rehabilitation.
Treatment should be comprehensive and adjusted to each patient's progress. Medication, therapies or procedures should not be started without guidance from a healthcare professional.
How can you live with complex regional pain syndrome?
Medical follow-up and continuing treatment are important for maintaining mobility and improving quality of life. The following measures may help manage the condition:
When should you see a doctor?
Seek medical evaluation if pain persists after an injury or surgery, is more intense than expected, or occurs alongside changes in the temperature, color or sensitivity of a limb.
You should also seek care if you experience swelling, stiffness or difficulty moving the affected arm or leg. An evaluation can help identify the cause of your symptoms and determine whether treatment or rehabilitation is needed.
If pain occurs suddenly along with sudden weakness, loss of sensation, difficulty speaking, chest pain or shortness of breath, seek emergency medical attention. These symptoms may indicate another condition that requires immediate care.

Frequently Asked Questions About Complex Regional Pain Syndrome
1. Can complex regional pain syndrome be cured?
The course of the condition varies from person to person. Some patients improve over time with treatment, while others may experience persistent pain. Early care and rehabilitation may help manage symptoms and preserve limb function.
2. Which parts of the body can be affected?
It usually affects one limb, such as a hand, arm, foot or leg. In some cases, symptoms may spread to other areas of the body.
3. What is the difference between Type 1 and Type 2?
Type 1 occurs without evidence of a specific nerve injury. Type 2 develops after an identifiable nerve injury.
4. Can complex regional pain syndrome develop after surgery?
Yes. It may develop after surgery, a fracture or another type of injury. However, not everyone who undergoes these procedures develops the condition.
5. How long does complex regional pain syndrome last?
Its duration varies. Some people gradually improve, while others may experience symptoms for months or years. The course depends on several factors and requires medical follow-up.
In addition to pain, it may cause changes in skin temperature and color, swelling, extreme sensitivity and difficulty moving the affected area. Recognizing these symptoms and seeking medical evaluation can help patients receive timely care.

The exact cause of complex regional pain syndrome is not fully understood. It may involve an abnormal response of the nervous system and other mechanisms involved in pain regulation after an injury.
Events that may occur before the condition develops include:
- Fractures and musculoskeletal injuries.
- Blows or trauma to a limb.
- Surgery.
- Nerve injuries.
- Prolonged immobilization of a limb.
- Type 1: formerly known as reflex sympathetic dystrophy. It occurs without evidence of a specific nerve injury.
- Type 2: formerly known as causalgia. It develops after an identifiable nerve injury.
What are the symptoms of complex regional pain syndrome?
Symptoms usually affect the involved limb and may change over time. Their severity and combination vary from person to person.
Common symptoms include:
- Persistent pain or a burning sensation.
- Increased sensitivity to touch, pressure or temperature changes.
- Changes in skin color.
- Temperature differences between the affected limb and the opposite limb.
- Swelling.
- Changes in sweating.
- Joint stiffness or reduced range of motion.
- Weakness, tremors or difficulty moving the limb.
- Changes in hair or nail growth, or skin texture.

- X-rays: help evaluate bones and joints.
- Magnetic resonance imaging (MRI): helps examine tissues and structures in the affected area.
- Bone scans: may reveal certain changes in the bones.
- Nerve conduction studies: may be used when nerve function needs to be evaluated.
