Overview

Ulnar wrist pain is pain on the side of your wrist opposite the thumb. This pain can vary, depending on the cause. It may worsen when you grip something or twist your wrist. Ulnar wrist pain can be hard to diagnose because it can be linked to many different types of injuries.

Causes

A common cause of ulnar wrist pain is a fall onto an outstretched hand. This can break bones in the wrist. Sports like tennis, golf, and football can sometimes bend the wrist back too far and this can damage tendons and ligaments. Carpenters and plumbers may develop ulnar wrist pain because they often must use tools in small spaces that require awkward positioning of the wrist.
