Diagnosis of trigger finger doesn't require any elaborate testing. Your doctor or health care provider makes the diagnosis based on your medical history and a physical exam. During the physical exam, your doctor will ask you to open and close your hand, checking for areas of pain, smoothness of motion and evidence of locking. Rarely, your doctor may inject a numbing medication (local anesthetic) to reduce pain so that he or she can proceed with the physical exam of your fingers and hand.
