Clinical Causes: Previous injury or trauma to the upper limb, such as fractures, sprains, or surgeries. Lengthy immobilization or improper healing of injuries. Nerve damage or irritation following injury. In some cases, no clear initial cause is identified.

Key Symptoms: Persistent, burning pain that is often disproportionate to the original injury. Swelling and changes in skin color or temperature in the affected limb. Sensitivity to touch or temperature changes. Stiffness in joints and muscles, leading to reduced mobility. Changes in hair and nail growth patterns. Muscle weakness or atrophy over time. Tingling or numbness in the affected area. Trophic changes like shiny skin or skin that becomes thinner.

Diagnosis Path: Diagnosing CRPS I involves a combination of patient history, clinical examination, and ruling out other conditions. Doctors may perform various tests, such as bone scans, MRI, or nerve conduction studies, to look for characteristic changes. The Budapest criteria are often used to help confirm the diagnosis, focusing on the presence of continuous pain alongside other symptoms such as sensory, vasomotor, sudomotor, and motor/trophic abnormalities.

Treatment Protocols: Medications like pain relievers, nerve blocks, and topical agents. Physical therapy to maintain mobility and prevent contractures. Psychological support, such as cognitive-behavioral therapy, to cope with chronic pain. Desensitization and graded motor imagery exercises. Interventional procedures like sympathetic nerve blocks in some cases. Electrical stimulation, such as TENS (Transcutaneous Electrical Nerve Stimulation). In rare cases, surgical interventions or spinal cord stimulation might be considered.
