Yes, Greg - my son did have signs - he had what he thought was a sore under his tongue from having bitten it. He kept putting off going to the dentist because he was between jobs and no health insurance. It finally started to hurt so much that he did go and luckily the dentist recognized something suspicious and sent him to an oral surgeon who biopsied it and sent him to a maxillofacial surgeon. I hope your appt is soon and that everything goes well.
