Did you ever get this diagnosed? I have just completed my third tongue biopsy (no cancer), but I have had a sore on the end of my tongue which sounds similar to yours, small pebble size lump, whitish on the outside, hole in the middle, for 3 years! I have seen Dentists, Oral Surgeon, Physician and ENT. Not one Doctor can tell me what it is or what caused it. Extremely painful 24/7..well, maybe 18/7 (I can still sleep). Would love to know what you found out! Not a single treatment has helped, and now I think this third chunk from my tongue is going to yet make it worse. (which was so excruciating because your tongue does not stay numb for long periods of time, and they dont send you home with anything to keep it numb).I am hoping yours has gone away. I have searched the internet for 2 years, and you are the closest in similar traits that I have found to date! MView Thread
