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 has a number of possible causes, including:
- Falls. A common cause of ulnar wrist pain is a fall onto an outstretched hand, which may fracture bones in the wrist.
- Sports injuries. Certain sports — such as tennis, golf and football — can overextend the wrist and damage ligaments and tendons.
- Occupational risks. Using a computer mouse or keyboard in a position that causes stress on the wrist can lead to wrist pain due to overuse. Carpenters and plumbers may develop ulnar wrist pain, because they often must use tools in small spaces that require awkward positioning of the wrist.
