I had emergency surgery a little over a month ago due to a vaginal tear. I lost a tremendous amount of blood and almost 'bled out' according to my doctor. While I was awaiting surgery my teeth began to clack together...very hard...not CHATTERING. I have at least ten veneers and four porcelein crowns. The next day after surgery I felt extreme pain when trying to eat. It has gotten progressively worse since then. I think now that I have damaged my trigeminal nerves on both sides of my face. I cannot eat or drink...I have lost over 15 lbs. (which I can ill afford). Has anyone else ever experienced this?
