In addition to the above I have found it very useful to brace the wrist. This is particulary effective when overuse of the wrist is a predominant factor. Add in icing and waiters tip stretches plus avoidance of aggravating factors from your subjective assessment. When this fails go to the neural tension, cervical joint assessment route (hardly ever a factor). If no progress, ultrasound investigations may be useful in determining if a tear is present and orthopedic involment is required.
