G90.522

Clinical Causes: Recent injury or trauma to the left leg, such as fractures, sprains, or surgeries Minor injuries that may seem insignificant but trigger the syndrome Nerve injuries or disruptions in nerve signaling pathways In some cases, no clear precipitating event is identified Certain medical conditions and surgeries may also increase risk

Key Symptoms: Persistent, severe pain in the left lower limb, often described as burning or stabbing Swelling and changes in skin color or temperature of the limb Sensitivity to touch or pressure (allodynia) Abnormal sweating or excessive sweating in the affected area Skin changes, including shiny appearance and changes in hair and nail growth Reduced or increased limb movement leading to stiffness or weakness Muscle atrophy over time and joint stiffness Tingling or numbness in the affected limb

Diagnosis Path: Diagnosis of CRPS Type I involves a combination of clinical evaluation and ruling out other conditions. Healthcare providers typically consider history of injury, physical examination, and symptom patterns. Additional tests that may assist in diagnosis include bone scans, sympathetic nervous system tests, and MRI scans. Although no single test definitively confirms CRPS, these investigations help support the diagnosis and exclude other causes of limb pain.

Treatment Protocols: Pain management with medications such as analgesics, corticosteroids, and nerve blocks Physical therapy to maintain or improve limb function and mobility Psychological support or counseling to cope with chronic pain Desensitization techniques and sensory re-education Gradual, supervised exercises to prevent stiffness Interventional procedures like sympathetic nerve blocks or spinal cord stimulation in severe cases Alternative therapies such as acupuncture and biofeedback, under medical supervision
