I've had this lump on my right side of my cheek bone but it is not protruding out and it is not swollen or any sign of pimple. It is just notice for nearly a week. When I touch that part, I can feel there is some sort of lump under my cheek and if I press it, I feel pain. When I check inside my mouth, I couldn't see any ulcer. I can still eat my regular meals but if I touch it, pain. Please tell me what I should do before is too late.Any opinons on this will be appreciated, thanks.
