Hello,
You describe symptoms of an infection not fully treated and going through different stages. Realize that the source of the infection has not been eliminated since you have not removed or treated the tooth. You may be developing a resistant infection. Infections spread and can cause a generalized swelling or pool into an area with a pocket of pus. This may need to be drained and require additional antibiotic treatment.
Lymph nodes can become swollen with dental infections present. Infections flare up and calm down with antibiotics and anti-inflammatory medications, but you risk a more serious ,long term infection being more difficult to control. Stay on the anti-inflammatory medication
Motrin. Make an appointment with your
dentist before the condition gets worse. Once you treat the tooth, I expect your dental health to improve, since this is most likely related to the abcessed tooth. Consider having a dental exam and cleaning for an overall evaluation of your dental health.
I understand your concern with cost and not having dental insurance, but dental conditions untreated tend to get worse. This means additional dental treatment and more costs. Many dental offices offer payment plans or work with health credit cards that offer a payments plans with a period of no interest .
Thank you for your inquiry. I hope you seek treatment and feel better soon. Please ask any additional questions and I will be glad to offer assistance.
