Patients with algoneurodystrophy may present with the following characteristics:
- Demographics: It can occur in individuals of any age but is more commonly diagnosed in adults, particularly women aged 40-60 years[1].
- Precipitating Factors: A history of trauma, surgery, or immobilization of the affected limb is often noted. However, some cases arise spontaneously without any identifiable trigger[2].

Signs and Symptoms

Pain

• Severity: Patients typically report severe, burning pain that is disproportionate to the initial injury. The pain may be constant or intermittent and can worsen with movement or touch[3].
• Location: In the case of M89.021, the pain is localized to the right upper arm but may also radiate to other areas, including the shoulder and hand.

Sensory Changes

• Hyperesthesia: Increased sensitivity to stimuli, where even light touch can provoke significant pain.
• Allodynia: Pain resulting from stimuli that do not normally provoke pain, such as a gentle breeze or clothing touching the skin[4].

Swelling and Changes in Skin

• Edema: Swelling of the affected arm is common, often leading to a feeling of heaviness.
• Skin Changes: The skin may exhibit changes in color (red or pale), temperature (hot or cold), and texture (shiny or thin). Hair and nail growth may also be altered, with hair becoming sparse or growing abnormally[5].

Motor Dysfunction

• Reduced Mobility: Patients may experience stiffness and reduced range of motion in the affected arm, making it difficult to perform daily activities.
• Muscle Atrophy: Over time, disuse of the affected limb can lead to muscle wasting and weakness[6].

Psychological Impact

• Emotional Distress: Chronic pain conditions like algoneurodystrophy can lead to anxiety, depression, and a decreased quality of life due to the persistent nature of the symptoms and the impact on daily functioning[7].

Conclusion

Algoneurodystrophy (ICD-10 code M89.021) presents a complex clinical picture characterized by severe pain, sensory changes, swelling, and motor dysfunction localized to the right upper arm.
