My cute Ethan has Geographic Tongue

A fairly-common tongue condition of unknown cause manifesting as multiple, flat, irregular, red lesions of the tongue dorsum; after proper diagnosis, no treatment is necessary.

another description of Geographic Tongue

Geographical tongue occurs when areas of the tongue become smooth and pink and irregular in shape. Against the normal furry surface of the tongue these areas create the appearance of a map, hence the name. No one really understands what causes it to happen in the first place but it doesn't need any treatment.
In most cases geographical tongue isn't painful. If it is then the changes you're seeing may well be because of another condition. Oral thrush can cause areas of the tongue to become sore and creamy white patches to appear as well. Using an oral anti-fungal mouthwash or lozenges will clear this up quickly.

I have read online from people who have this said it hurts and is very painful; even though doctors say it isn't. They said they have trouble eating pineapple due to that sets it off the worsted. No wonder Ethan hates pineapple along with other juices. only recently he started to drink one sippy of really water down juice. Poor little guy. Sometimes it just starts to bleed for no reason. I have seen that happen to him. I thought he bit his tongue before I knew what he had. I nephew who is a month older then him also has it. So I blame my husbands side of the family for this. (Joking of course)
