I have a sore left jaw, upper and lower, and it radiates toward my ear, and I get a headache. I went to the Chiropractor and he told me my neck was all messed up, but if it didn t go away to see an MD for possible heart attack. I am 47 with no known heart problems. When it happened, I was chewing gum and thought I broke out a filling. It started hurting in my upper and lower jaw and I couldnt tell which tooth it was...
