Physical examination To diagnose<unk> , physicians perform a battery of tests in which they place pressure on the affected area while asking the patient to move the<unk> , wrist, and fingers. Diagnosis is made by clinical signs and symptoms that are discrete and characteristic. For example, when the<unk>  fully extended, the patient feels points of tenderness over the affected point on the<unk> . The most common location of tenderness is at the origin of the extensor carpi radialis brevis muscle from the lateral epicondyle (extensor carpi radialis brevis origin), 1 cm distal and slightly anterior to the lateral epicondyle. There is also pain with passive wrist flexion and resistive wrist extension (Cozen's test). Medical imaging X-rays can confirm and distinguish possibilities of existing causes of pain that are unrelated to<unk> , such as fracture or arthritis. Rarely, calcification can be found where the extensor muscles attach to the lateral epicondyle. Medical ultrasonography and magnetic resonance imaging (MRI) are other valuable tools for diagnosis but are frequently avoided due to the high cost. MRI screening can confirm excess fluid and swelling in the affected region in the<unk> , such as the connecting point between the forearm bone and the extensor carpi radialis brevis muscle.
