Same as mine. Diagnosed as dysplasia. It spread quickly. And I'm now waiting to have it removed. You need a referral to a maxillofacial specialist who will probably do a biopsy just to be sure. Don't wait , sort it out soonest. If you had bit your tongue you would have known at the time. Mine felt like that and stayed sore for two weeks before I took any action. Hope this helps. Good luck.
