My wife has had chronic pain of bilateral hips and knees. She has seen two orthopedics and has had surgery of the right hip for a torn labrum. She is still having pain which is worsening and recently had imaging in all affected areas. We have reached a dead end and have been advised to see a rheumatologist. She has not seen one, but has tested negative for RA factor, normal sed-rate, and negative ANA. What do we do? Could it be a rheumatologic problem?
