It sounds like your TMJ area has been effected temporarily by the need to open so wide. I would take Advil at this point. Avoid causing any pain by opening to wide--baby it at this time.I would give it about a month to calm down, if it doesn't then I think you need to see a doctor that specializes in this area.
Thanks for your quick reply. I just had visions of never being able to open my mouth correctly again!!!
spounds like jaw musclulature, which is intricate and delicate. advil, massage, stretch, just like any other painful muscle. you csan also madssage inside your mouth where it is sore.
