Complex Regional Pain Syndrome Q & A

What is Complex Regional Pain Syndrome?

CRPS is a chronic nerve disorder that occurs when pain that was initially caused by an injury lasts long after the damage heals. Another characteristic of CRPS is that your ongoing pain is worse than the degree of pain caused by the trauma.

There are two types of CRPS. CRPS-I is caused by any type of injury, such as a fracture or soft tissue sprain. CRPS-II develops after you sustain direct nerve damage.

What symptoms develop due to Complex Regional Pain Syndrome?

CRPS-I and CRPS-II share the same symptoms. The primary symptom of persistent pain usually affects one limb. However, the condition is progressive, and the pain that begins in a hand or foot often spreads to include your arm or leg. CRPS causes severe pain that’s described as burning pain or like sharp needles.

The affected area often becomes hypersensitive, making even a soft touch feel painful. The nerve damage underlying both types of CRPS affects your blood vessels, leading to changes in your skin color, temperature, and texture.

You may also experience symptoms such as:

  • Stiff joints
  • Swelling in the affected limb
  • Excessive sweating near the injury
  • Changes in hair growth on the affected limb
  • Changes in nail growth on the affected fingers or toes

Muscles are affected as the condition worsens, leading to spasms, muscle atrophy, and loss of coordination.

What is the treatment for Complex Regional Pain Syndrome?

A variety of treatments is available to support the different aspects of CRPS. Dr. Aggarwal customizes your treatment plan to include one or more of the following:

Physical therapy

The structured exercises you’ll learn in physical therapy are important to reduce circulatory problems and maintain muscle strength and coordination. Rehabilitation may also prevent or reverse the central nervous system changes that lead to hypersensitivity.


Dr. Aggarwal may prescribe one of several possible medications to treat symptoms such as pain, inflammation, and muscle cramps. He also offers intravenous infusions with Lidocaine and Ketamine which have proven to benefit the patients suffering from CRPS.
