Identify any problem in the skeleton and there will be areas that need to be addressed, above and below that problem area. There are no isolated problem areas because the musculo-skeletal system is like a spider web. Pull or tug on or mess with any area of the web and there will be negative repercussions throughout it. Many things need to be untangled and addressed to remedy one, seemingly isolated symptomatic area. This is another reason why treating a symptom as "the problem" does not work. This is also the reason why hip and lower back pain often go together.
