Pain that is out of proportion to the injury and may be sympathetically maintained points to Complex Regional Pain Syndrome. This condition often follows a limb trauma and features severe, persistent pain that seems disproportionate to exam findings, along with autonomic and trophic changes such as color or temperature shifts, swelling, sweating, and changes in skin, hair, or nails. Sensory symptoms like allodynia and hyperalgesia are common, and motor changes such as reduced range of motion or weakness can occur. The concept of sympathetic maintenance means the sympathetic nervous system contributes to sustaining the pain, which is why interventions like sympathetic blocks can provide relief. In contrast, osteoarthritis involves pain from joint degeneration and typically correlates with use or wear; carpal tunnel presents with numbness and weakness in the median nerve distribution rather than disproportionate pain; gout causes sudden, intense inflammatory joint pain with swelling and redness and has a clear metabolic trigger, rather than a chronic sympathetic-driven pain syndrome.
