Complex Regional Pain Syndrome I (CRPS I) is a chronic pain condition that typically follows an injury or trauma, characterized by severe pain, swelling, and changes in the skin. The ICD-10 code G90.512 specifically refers to CRPS I affecting the left upper limb. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of CRPS I

Definition

Complex Regional Pain Syndrome I is a type of chronic pain condition that arises after an injury, surgery, or other trauma, without the presence of a confirmed nerve injury. It is characterized by a range of symptoms that can significantly impact a patient's quality of life.

Symptoms

The symptoms of CRPS I can vary widely but typically include:

• Severe Pain: Patients often report intense, burning pain that is disproportionate to the initial injury.
• Swelling: The affected limb may exhibit significant swelling, which can fluctuate over time.
• Changes in Skin Color and Temperature: The skin may appear red, pale, or mottled, and temperature changes can occur, with the affected area feeling warmer or cooler than the surrounding skin.
• Altered Sensation: Patients may experience hypersensitivity to touch (allodynia) or changes in sensation, such as tingling or numbness.
• Motor Dysfunction: There may be weakness, tremors, or difficulty moving the affected limb, leading to functional impairment.

Diagnosis

Diagnosis of CRPS I is primarily clinical, based on the patient's history and symptomatology. The following criteria are often considered:

• A history of an initiating event (e.g., injury or surgery).
• Symptoms of pain, swelling, and changes in skin color or temperature.
• Exclusion of other conditions that could explain the symptoms.

Pathophysiology

The exact cause of CRPS I is not fully understood, but it is believed to involve a combination of neurogenic, inflammatory, and psychological factors. The condition may result from abnormal responses of the nervous system to injury, leading to excessive pain signaling and changes in blood flow and tissue metabolism.
