Does this only happen to me?

Never happened to me, but about 6 months ago I started having an issue where sometimes when I yawn if feels like I pull a muscle on my right side, or like a tendon popping across a bone when under tension, and it hurts bad and I snap my jaw shut real quick. Only happens on a big yawn and not too often, but very annoying and painful.

But yeah, I'd say maybe you should check with a doc.
