Oral cancer is not characterized by a sudden outbreak of numerous sores, which sounds more like a herpes simplex outbreak. Stress can cause herpes to manifest itself if you have it. Your post certainly sounds like you are under stress... At your age you are also not a likely candidate for this type of cancer unless you are a chronic chewing tobacco user, and you didn't mention anything about the risk factors in our life. Like the others have said, go to see a different ENT, or someone who specializes in oral pathology. They will be able to tell you what's what. Any ointment that the doctor gave you for use in your mouth is likely only to reduce the effects of the symptoms and not to treat disease. My guess is that he gave you something to take away the discomfort of this herpes outbreak and is waiting for a couple weeks to go by when it will clear up on its own usually. There is no treatment for it and it has to run its course.
