im a 16 year old female and when i was playing volley ball i hit the ball and i felt a snap in the back of my head behind my left ear. It was like a airhead snapping and then followed by a sensation of warm water flowing down my head even though i was not wet at all. this has happened two more times and i told my mother but she really has no clue and doesn t feel its necessary to take me to the doctor. I really would like to know what this is. There is no pain with it, but a strange tingling sensation afterward.
