For the past two weeks I have been having a real hard time eating normal. In the mornings, I could only open my mouth about an inch. It starts hurting towards the left rear side of my jaw. When I open it all the way, it tends to "pop" then to close it "pops" back to where it was. A man told me that my jaw was a bit out of place and he somewhat put it back. Do you have any idea what can I do to fix my problem?
