Hi, Penny
Welcome to our forum. It sounds like you've got a lot of stress going on in your life right now. I want to wait hear what the dentist has to say before I comment. It could be that taking care of dental infection will put you in good order fairly quickly. Be sure to ask for an oral cancer screening.

If you have a university with a dental school nearby, you may be able to get future problems attended to at low cost at the student clinic if you don't have dental insurance.

Keep breathing and let us know how the dental visit goes!
