Key Points

• Lack of use of local injection test to confirm the diagnosis may lead to miss the diagnosis of PMS of myofascial origin.
• Piriformis muscle syndrome should be diagnosed on the basis of clinical symptoms, specific physical examinations, and positive response to local injection.
• Sciatic nerve entrapment is not a must in the diagnosis of PMS and PMS is mostly myofascial in origin.
