Hello, This is Dr. Klarida Papaqako answering your question. Fortunately, the majority of tongue problems are not serious and most can be resolved quickly. --From what you are describing, looking at the age of your daughter, looks like is something viral, since it has affected your husband as well. In this case, if I was your caring doctor, I would recommend to continue with symptomatic treatment (analgesic gels, cold foods), watching carefully her general condition (fever, body rash, tiredness). If any of the general conditions symptoms mentioned above do not appear, it should resolve itself within a week time. If not, I would recommend to see a physician. --Another common problem that may be, in case both your daughter and husband have used antibiotics lately, or have other signs of thrush elsewhere, is a thrush infection. This is less likely then the first possible diagnose, but this case you will need to use a antifungal oral cream. So summarizing, my recommendation is to watch the general condition of both your daughter and husband for 2 other days (5 days with these symptom) and give oral and topical analgesics to help with the pain. If it is not better but getting worse by then (normally it should start getting better) then consider seeing a physician, who will see it and recommend appropriate labs. Hope this helps. Regards.
