[|Human|] my 4 year old son has a very rounded ball of skin (now approx 3/4mm on his inside lower lip. It is the same colour as the rest of his mouth but has been there and growing for around 4 months, maybe slightly longer. It doesn t hurt but is definitely getting bigger. He has a fungal toenail infection in each toe on one foot which doesn t seem to be going despite topical medication - he s had it well over 2 years but is otherwise very healthy and fit. What is it?
[|AI|]  Hi Dear, Welcome to Chat Doctor. Understanding your concern. As per your query your son have symptoms of lump on the inner lip which is mainly because of viral infection such as herpes, canker sore or frictional keratitis. I would suggest you not to panic about it. Maintain oral hygiene by brushing and flossing daily. Do Listerine mouthwash rinses. Your symptoms will resolve in 10-14 days.  Chat Doctor.  Avoid hot, sharp, spicy food. Take ibuprofen if it is tender to touch. If symptoms keeps on persisting visit oral physician once and get it biopsied and examined. You should start treatment after complete examination. Hope your concern has been resolved. Get Well Soon. Best Wishes,
