Patient Characteristics

Patients with algoneurodystrophy may present with the following characteristics:
- Demographics: It can affect individuals of any age but is more commonly seen in adults, particularly women aged 40-60 years[1].
- History of Injury: Many patients report a history of trauma, surgery, or immobilization of the affected limb prior to the onset of symptoms[2].
- Psychosocial Factors: Psychological factors, such as anxiety and depression, may also play a role in the development and persistence of symptoms[3].

Signs and Symptoms

Pain

• Severity: Patients typically experience intense, burning pain that is disproportionate to the initial injury. The pain may be constant or intermittent and can worsen with movement or touch[4].
• Quality: The pain is often described as throbbing, aching, or sharp, and may be accompanied by allodynia (pain from stimuli that do not normally provoke pain) and hyperalgesia (increased sensitivity to painful stimuli)[5].

Swelling and Changes in Skin

• Edema: Swelling of the affected limb is common, often leading to a noticeable increase in size compared to the unaffected limb[6].
• Skin Changes: The skin may exhibit changes in color (red or pale), temperature (warm or cool), and texture (shiny or thin). These changes can be attributed to alterations in blood flow and sympathetic nervous system activity[7].

Motor and Sensory Changes

• Motor Dysfunction: Patients may experience weakness, tremors, or difficulty with coordination in the affected limb. This can lead to decreased range of motion and functional impairment[8].
• Sensory Disturbances: There may be altered sensations, including tingling, numbness, or a feeling of heaviness in the affected area[9].

Other Associated Symptoms

• Hair and Nail Changes: Patients may notice changes in hair growth (either increased or decreased) and nail growth (thickening or ridging) on the affected limb[10].
• Bone Changes: Osteoporosis and bone density loss can occur in the affected area, leading to an increased risk of fractures[11].

Conclusion

Algoneurodystrophy (ICD-10 code M89.062) presents a complex clinical picture characterized by severe pain, swelling, and various sensory and motor changes in the left lower leg.
