If you have oral cancer, can the symptoms come and go or is it a constant feeling. Burning lips, teeth ache, gums swell, facial pain, throat feels like its swelling, roof of mouth is very sensitive, and light headed. All my symptoms seem to come and go through out the day. I'll feel ok one sec then 30 min later its terrible. Does this sound like oral cancer. I dont have any lump or bumps, but I do have what my ENT called an infection on my adenoids, or a large red mass, he said. Can anyone give me some info on symptoms.
