Hi, I am having trouble moving my right side of my jaw, hard to open my mouth. My left side is just fine. If I work on it, I can open my mouth more, but it is painfull. This is the second time on the same side in the lst 2 months. I don't take medications, I have not had any dental work done, and no cuts, and I have had a tetnas shot with in the last year. Also, no drugs.
