You are asking questions that no one here can really answer. Everyone has different symptoms, you have got to see what a doctor who has looked in your mouth, samples tissues etc. has to say. Anything else that we tell you is going to be speculations and guessing by lay people. You are going to have to wait for the doctor's conclusions. So far though you sound like someone that has infections (viral or bacterial). The emotional ups and downs of waiting are certainly not easy, but you've got to deal with it.... the alternative is just to add anxiety issues to the fire.
