Greater Trochanteric Pain Syndrome
This is a general term to describe pain on the lateral aspect of the hip and can cover pain generated from a number of areas.
The trochanteric bursae can be a common cause of lateral hip pain; they provide protection to several tendons against the greater trochanter and can become inflamed causing discomfort particularly with overuse.
However the gluteus medius and minimus attach toward the lateral aspect of the hip and problems with these tendons can cause symptoms in the same area.
