Question

Why do violent sneezes cause you to feel pain in seemingly unrelated body parts (like your arms/hands)?

A sneeze often involves a rapid and severe spasm of the entire chest. Aside from the direct effects this can cause a sudden change in your heart rate and blood pressure. A sudden spike or trough in blood pressure is probably causing any sensation you feel in your extremities.
