To diagnose the underlying cause of ulnar wrist pain, your doctor may move your wrist or hand into different positions to see what hurts. Imaging tests like CT, MRI, and ultrasound scans may also be needed.

Depending upon the cause of your ulnar wrist pain, you may be a candidate to undergo motion analysis of your wrist to see if the tendons are working properly. For example, in tennis players, the double-handed backhand in the non-dominant wrist or during the forehand in the dominant wrist may cause pain due to a tendon problem.
