Hello, doctor, this is Vanness. I m wondering if I had a broken/dislocated/bruised coccyx since half a year ago. Every time after I sit on a hard surface for more than an hour, I can feel the pain from the area around the coccyx. Still I m able to run, stand, simply walk or jump as much as I wish. Could you please tell me what s wrong with my coccyx? How should I diagnosis it? What can I do?
