I managed to work myself into a tizzy last night, when I realised I was getting pain in my jaw when I yawned or opened my mouth wide....

It is like a muscular pain around the lower jaw joint running up to my ear.
By god, I hope it is just sinus congestion and not me developing TMJ. I've never had TMJ problems, or headaches and I don't want to start

That was one of the reasons for asking my dentist not to correct my bite!
So..... I have taken some decongestants and am keeping my fingers crossed...
