Sara is a 49 year old lady who has suffered from chronic pain for many years. When I first reviewed her several years ago she was unable to walk without significant pain. A diagnosis of hip impingement syndrome and she had an arthroscopic hip operation which relieved her right hip pain significantly. She had similar symptoms on the left hip and an operation helped her symptoms on the left side. She was able to walk and over the next year noticed the pain around her hip joints had decreased but she started experiencing pain in the buttock regions that travelled down the right leg.
