Hi, I am a 19 year old female and for the past 3 days, my jaw has not been functioning normally. I had no history of injuries and all of a sudden my jaw feels sore and "tired". When I relax, it feels like its moving forward and I forcefully have to move my jaw back but it feels like my jaw is sore. Do I need surgery? This happened for no reason. Can someone's jaw move for no cause?
