Tanner's foot

A few days ago, Tanner started complaining about something on the bottom of his foot. I took a look and was pretty surprised at what I found. He has this wart thing on the bottom of his foot that looks like a mound of skin with yellow cottage cheese underneath.....paints a pretty picture, huh.....I wasn't sure though what it was so I took him to our doctor to be sure. He said it is just a certain type of wart and that we could try and treat it with something over the counter. We got this thing at the store that sort of freezes it. It looked weird and sort of stung, but we'll see if it works.
The pictures don't really do it justice. It's pretty big and very strange looking and it's very sensitive to touch which stinks when you're trying to walk.
