Complex regional pain syndrome type 2 (CRPS 2) is a chronic pain condition that is caused by damage to the peripheral nervous system. It is characterized by severe burning pain, swelling, and changes in skin color and temperature in the affected area. It is often accompanied by changes in sensation, such as numbness, tingling, or hypersensitivity. CRPS 2 is also known as causalgia.

The symptoms of Complex Regional Pain Syndrome Type 2 (CRPS-2) can vary from person to person, but typically include:

- Burning or aching Pain that is out of proportion to the severity of the injury

1. Physical Therapy: Physical therapy is an important part of treating CRPS type 2. It can help to reduce pain, improve range of motion, and increase strength.

2. Occupational Therapy: Occupational therapy can help to improve function and reduce pain. It can also help to improve coordination and balance.

3. Medications: Medications such as non-steroidal anti-inflammatory drugs (NSAIDs), opioids, and anticonvulsants can be used to help reduce pain.

4. Nerve Blocks: Nerve blocks can be used to block the transmission of pain signals from the affected area.

3. Nerve damage
4. Infection
5. Stroke
