Hello, I am glad to offer some advice. Your continued discomfort raises the concern of an infection. An abscess can cause swelling that could appear as bumps and cause pain. Some swellings can drain and cause irritation. The teeth can be evaluated by a dentist. X-rays can help diagnosis infections. If the bumps are hard and located on both sides of the mouth they may be tori. This extra bone that is of no concern and should not cause symptoms. A dentist can diagnosis this condition. You may have been treated with antibiotics and sometimes this disturbs the bacteria balance in your mouth. Your gums can feel sore, sensitive and be red. This condition can require anti-fungal medicine. You may wish to check back with your treating physician since you report throat discomfort and voice change. Some viruses can reoccur or be resistant. It is a good idea to rule out a dental infection with a dental visit. Infections can put stress on your entire body and you can experience general discomfort if left untreated. Infections can be very serious. You are wise to question why you are not feeling much better. Continued mouth breathing causes throat irritation. Are your sinuses clear? I am more concerned with your dental health if you have not had a recent dental exam and are not current on your regular recall visits. As always, practice good oral hygiene: brushing, flossing and rinsing. Keep well hydrated and healthy diet with balanced vitamins. You would need the mole looked at by a dermatologist if changes are occurring and pain continues. I hope you find my suggestions helpful and that you follow my recommendation to see a dentist and your doctor. You need to review your complete medical history with all treating doctors. I hope you feel better soon.
