DS2 is 19mths and about a month ago I noticed a small lump in his lower lip. Initially I thought it was from him falling over and putting his teeth into his lip but it's more in the corner of the mouth and it hasn't changed size. It's mostly within the lip (that is, it doesn't stick out) and feels as though there is a raw grain of rice in the lip (very solid). If you look really closely you can see his lip is slightly lumpy there and it's more obvious when he smiles or cries as his lip gets pulled tighter and the skin lightens in the spot where it stretches over the lump.
I'm taking him to the GP on Friday to get it looked at but am just wondering if anyone has any experiences of lumps on lips and if so, what they were?
