Tennis Elbow
Diagnosis

Doctors can usually diagnose tennis elbow through a physical exam alone. Patients are tender at the outer elbow, in the area of the lateral epicondyle, and it hurts to extend the wrist, especially against pressure. Elbow X-rays may be ordered if the doctor suspects abnormal calcium deposits, bone spurs or a joint problem. A diagnostic ultrasound or an MRI is sometimes ordered if the diagnosis is unclear or the patient doesn't improve with treatment.
