Hello, You are already taking a fever reducing medication. Gums can react to various medications especially if your mouth is dry or you have gastric upset from the medications. I suggest a dental exam. If you have not had a regular dental visit, then a basic cleaning could help resolve your inflamed gums while the condition of your teeth would be evaluated and infections diagnosed. Infections in the mouth can cause these symptoms. A prescription medication such as an antibiotic may be necessary. Make sure you are well hydrated, keep up with good daily oral care and add salt water rinses to help soothe the gums. Proper nutrition and balanced vitamins are important. Vitamin E can be soothing. I appreciate your inquiry with HealthcareMagic. I hope my answer is helpful and you will schedule a dental visit as suggested. I would be glad to answer any additional questions. Thank you and I hope you feel better soon.
