Doctors usually diagnosed based on physical examination and symptoms, no need for testing. During the examination, the doctor will ask you to hold, open hands, to check the area on your hand, motion and joint stiffness. Your doctor may also touch your palm to see if there is a tumor blocking the tendon movement. If tumor is related to trigger finger, it will move simultaneously with finger movement, because tumor sticks to finger tendons.
