Hi, I am really scared!
I think I may have an ulcer or worse, mouth cancer. I have had my 4 back teeth on left hand side of my mouth for a couple of days however, they only began to hurt after eating. Now on the 3rd day of this, my ear is starting to ache. Also today after brushing my teeth I noticed a bump on my gum, on the same side of my mouth. Is this cancer?
