For almost a year now I have had a knot on the side of my face directly in front of my ear. It feels like the bone is coming out of place when I open my job. It pushes my lower jaw to the left. I do grind my teeth and because of being anemic I frequently chew ice. I am currently pregnant and this is becoming painful. I wake up very sore in the morning and after chewing I sometimes cannot close my mouth normally, like my teeth don't come together right. What can I do?
