Hi people, I really don't want to scare anybody but once you have an injury or at least something went wrong with your jaw go straight to a doctor. I'm not myself a doctor nor do I have any degrees in medicines, but for me it really sounds that everyone here should go and visit a doctor about this!
The chances that your problems are going to disappear but themselves without any help are very and very tiny, mostly each time one has a problem with his or her jaw and is not treating it - well, these people end up not as good as they would want to end. I'm telling one more time that I don't want to scare anybody, I just want you to feel well, and that’s why I'm here. You should know that the jaw is one of the most complex joints in one’s body so you should do anything possible to avoid any kind of problem with it, and if it appeared then you should treat it as soon as possible. I have found on the internet some information about your problem, what you can do until you're going to visit the doctor: use heat and use ice, also i found out that “Ibuprophen” helps too as well as having a soft diet. It's only up to you how you're going to act, but I just want to help.
Good luck with that and be healthy!
