I have had throbbing pain on the left side of my jaw and some stiffness in my neck for about a week now, but I can open my mouth and what not like normal. I can be a hypochondriac at times when I read in to thing. Would I defiantly be able to tell? and would both sides of my jaw be in pain??
How long ago did you get your Tetanus Booster? I am not a doctor, but the smart thing to do would to be to visit a doctor.
In the lock jaw there is difficulty in opening the mouth and sometimes when you open you mouth then you are not able to close it. The pain and stiffness can be due to some infected tooth or some trauma. Sometimes when the wisdom tooth is coming you have these types of symptoms. So visit your dentist to get the diagnosis made and for more information on TMJ disorder you can read the following very informative website article
