Doctors diagnose biceps tendinitis by taking the patient's medical history, performing a physical exam, and evaluating imaging studies – usually X-rays, though sometimes MRI or ultrasound. The physical exam typically reveals a sore spot on the front of the shoulder, and patients experience pain with lifting and actions such as throwing. X-ray images provide information on the shoulder joint, while an MRI or ultrasound can help the doctor check for other shoulder problems.
