<s>[INST] My daughter is 3, she has very swollen red gums, also what looks like a cold sore on her lip, and she has been running a fever for 4 days now. The dentist had seen her, said she had a virus and that is where the gums tissue swelling and stuff was from. Should I go ahead and take her to a doctor since she has been running a fever for 4 days?? [/INST] Thanks for your query, I have gone through your query. The swollen gums following history of fever can be a herpetic gingivostomatitis secondary to herpes virus infection. Nothing to be panic, it is a self limiting condition. It will subside in a week. You can take a symptomatic treatment like for pain you can take analgesics like ibuprofen (if you are not allergic), do saline gargling. For the soreness in the lip you can take topical analgesic like choline salicylate. I hope I have answered your query, take care. </s>
