The common signs and symptoms of a dislocated hip are acute severe pain in the hip – joint pain – or upper leg after a large-force trauma to the hip. Pain might also occur in the lower leg, knee, or back. Additionally, an individual usually cannot walk or move their leg. Numbness or tingling in the leg might occur with neurological damage, with bruising and swelling being evident. In short, you would know right away if you dislocated your hip with pain being severe and you would not be able to walk.
