Well, you definately have stamina to post all this lol. If I looked up any disease, yellow fever, malaria or any other very unlikely, I would have some symptoms, which does not mean I have them. Stay off Dr. Google! You may be reading too much into them, and making yourself ill. Alternately, if any symptom or suspicion, lasts more than two weeks, it should be checked out by seeing a doctor, and did good for doing so. See what the dentist says, ask for a referral to an ENT, especially one that has experience with cancer. How do you know you have no oral HPV? I always advise to get a full blood work up to rule out anything out of range, deficient, which can be a cause some of the ailments, indication of an infection, medical conditions. Change your toothbrushes often, in case there is a bacterial, fungal or viral infection, so not to reinfect yourself, and get tested for these too. In the meantime, try to enjoy youself, and some issues may disappear, and can always have here to come back to chick chat. Good luck.
