What are the symptoms of patellofemoral pain syndrome?

Answer:

Answer

The main one is pain behind your kneecap. That really is the giveaway that something is wrong. You might have some pain from sitting, walking, or running for a long time. The pain is sometimes worse walking downhill or down a flight of stairs. You might feel or hear snapping, popping, or grinding in the knee. Your knee may swell at times.
