Patient History: A 27-year-old woman presents with lower back and left hip pain that has been present for several years. The previous year, the patient consulted a spine specialist, who diagnosed a lumbar spine strain. The woman underwent several months of physical therapy and received trigger-point injections, without relief. Recently, she started seeing a different physical therapist, who thinks the pain is related to her hip and recommended hip radiographs.
The patient contacted her primary care physician, who ordered left hip radiographs and instructed her to follow-up with an orthopedist. Physical Examination: She denies any medical problems and does not drink alcohol or use tobacco. She does not take any prescription medications currently but admits, "I've taken more steroid dose packs than I can count" for her asthma and cat allergy. Which would be the next best test to order?…
