In my opinion, the best way to treat something is to first understand the why before attempting to fix it with the what. Try and have her understand why her hip is hurting. Is it pain radiating from her bone(s), or from the ligaments, tendons, muscles, etc in the area. A couple things I would suggest she focus on. 1. Daily exercise, such as walking at least 1 hour a day, is crucial. It increases blood flow to the lower body, lubricates joints, etc. 2. Another crucial and very neglected form of activity in western society is stretching/yoga. Make sure she is stretching daily, preferably after doing some sort of exercise like walking so that the muscles are warm and more malleable.
