While the various symptoms described earlier may be the first and best indicators of PPS, diagnosing PPS requires clinical information. Physicians normally only diagnose PPS after they complete a comprehensive medical history and physical examination. Part of this process includes ruling out other disorders that could explain the symptoms the person is having. It is very important to find a physician trained in neuromuscular disorders.
PPS is not always easy to diagnose. There are other medical conditions that may need to be considered including depression, shoulder osteoarthritis, chronic rotator cuff tear and progressive scoliosis causing breathing insufficiency can all be wrongly diagnosed as PPS.
