<s>[INST] My 4 year old daughter has been complaining about her tongue hurting this weekend. I took a look and found a sore that is red in the middle with a white ring around it on the side of her tongue on the underside. Should I take her to the dr (is it contagious or serious) or will it clear up on its own? [/INST] Thanks for your query, I have gone through your query. The red sore tongue with a white ring around it can be a geographic tongue or benign migratory glossies. Usually this occurs following stress or nutritional deficiency. Nothing to be panic, you can give topical anesthetic and analgesics like lidocaine and choline salicylate respectively. If it is not subsiding in a week, then consult a pediatric dental surgeon and get it evaluated. I hope my answer will help you, take care. </s>
