Dental Appointment.: You just need to be evaluated by a dentist. There are so many bad possibilities.

Infection: May be looking at a sign of the infection from your "bad teeth" now spreading to other organ systems. We can't fix this for you over the computer, nor can o find a cure in a pill bottle or o a pharmacist's shelf. You've been putting off seeking professional health care to the point where it's now putting you into danger. Call a local Dentist, make an appointment, and begin restoring your health.
