Ouch! But if its almost back to normal maybe there was some swelling? You should definetly get that checked out regardless. I've never experienced anything like that (getting kicked in a jaw), I've gotten Ax kicked to my right eye, and I've also taken side-kick to my neck.
The Jaw thing is scary though, I'd hate the thought of being in pain when trying to eat. I did have occassional locked jaw which was very uncomfortable and scary. Not being able to open my mouth, or close my mouth was very annoying.
Take care and hope you feel better!
P.S. I would highly recommend using a different blocking techniques
