Dear Bethany,

I had jaw surgery about 25 years ago to fix an alignment issue. Ever since I will get exactly the same pain and bump you are talking about. It comes on when I yawn or try and keep my mouth open wide for a while. I get this painful knot of muscle bunch up on the bottom of my jaw just behind my chin. I then have to massage the muscle for a few minutes to get it to calm down but it usually only lasts about 5 to 10 minutes. It�s about the diameter of a nickel and forms a noticeable bump

My doctors have all told me that the change to my anatomy due to the surgery is just causing the muscle to knot up under certain circumstances and I should not worry about it. Just massage it out and try and avoid those situations that cause it (yawning?).

If your pain is being caused by the same type of thing (change to anatomy due to surgery) you have nothing to be worried about. It�s just an annoyance you'll have to get used to while you deal with the bigger issues in your life.
