<s>[INST] Hi, my husband had a pus filled sore on his lip which he broke open. It smelled very bad and his mouth was stinking, too. Same night we had a sex and I didnt know that it could infect me. Two days later I had very bad fever with chills and 4th day my gums were really swollen and hurting.  I had my below the jaw lymph node also swollen and paining. I went to a dentist and he cleaned my teeth thinking that it could be gingivitis. Only 1-2 teeth gum area (incisor in lower jaw) was affected when I went to doctor. However, the same day after teeth cleaning I again started to have chills and fever. The next day also I had fever and again next day I had my upper jaw gums were swollen and had whitish ulcers at inner lower lip. I am very scared what should be done now. I have next appointment of dentist 2 days later. What this could be, please guide me. [/INST] Hi. Thanks for the query. From your explanation it looks like viral infection leading to chills and fever with swollen and blistered gums. It may or may not be due to communication of infection from your husband and needs investigation. So my suggestion is to consult an Emergency room and get an oral swab culture and a blood test done. For now, you can take Acetaminophen to reduce fever. Apply Lidocaine gel over the gums to reduce pain. You can also do warm saline gargles. Avoid spicy foods and take soft and bland meals. Maintain a good oral hygiene. Use a soft toothbrush to brush your teeth. If viral infection is ruled out you can be advised antiviral Chat Doctor. . Hope this helps. Regards. </s>
