Five days ago I had some bumps on the roof of my mouth. The next day they were gone and instead, a smooth red section took their place. For the last four days this has been very red and very painful. If anything at all touches it, it hurts a lot. The pain hasn't subsided and the redness and area doesn't seem to have started healing whatsoever. I've never had a mouth issue last thus long where I couldn't see any progress.
