I had a question, My best friend and I were eating dinner and his jaw cracked he has a sore pain on the right side of his jaw that only hurts when he swallows. He said the pain goes from his jaw to his temple.He has had this pain for two days now. He has never had TMJ, and it doesn't have any of the other symptoms of TMJ. Any idea or help that can be given to help stop the pain and find out what is causing it and what caused it initially?
