felt a movable mass above my left knee. would move in one direction whent flexed and another when extended. woke up one morning in incredible pain, unable to use leg, went to DR, passed out and taken to ER, all vitals are normal, 4 days later quad is stiff, still cant bend knee, on crutches
It is a bursa or ganglion-like cystic lesion needs USG/FNAC test for confirmation and surgical excision is usually done for relief!all the best...........
