Medical insightX😷 on Instagram: "The psoas sign is a clinical indicator of irritation of the iliopsoas muscle, often seen in appendicitis. To check it, the patient lies on their left side while the right hip is extended (or they lie on their back and you lift their right leg). Pain during this movement suggests inflammation near the psoas muscle, like from an inflamed appendix. It’s a classic exam trick for diagnosing appendicitis! 🩺✨ #psoas #psoasmuscle #pain #appendicitis #inflammation"
