I have a white sore in my mouth. Way in the back on the area where the top of my jaw intersects with the bottom of my jaw on the left side. I have had it for literally at least 3 months and it will not heal. It hurts so bad. The sore itself hurts, but it is making my whole jaw ache. Also my left ear is swollen at the opening. It is almost swelled shut. I am not sure if they are related. I do not have insurance so that is why I have not seen a physician. I do not even have a regular doctor. I don't want to go to the ER because it is not an emergency. Any ideas on how to get it to heal?
