A twinge is a sudden, sharp, localized pain. It's usually brief and often unexpected. Think of it like a quick electric shock in a specific area. Unlike a dull ache, a twinge is sharp and intense but doesn't last long. Imagine suddenly feeling a sharp pain in your back when you bend over. A twinge can be caused by a muscle spasm, nerve irritation, or other minor injury. It is often fleeting and doesn't require medical attention.
