(Gross) wart on foot

A while ago i posted this picture of my wart that i didn’t know was a wart until people on eve told me it was. This was it in early November

It’s been here since the summer. This is it now

Is it healing or getting worse. And why won’t it go away?!? I put tea tree oil on it and NOTHING! I mean it’s my foot so I’m not really concerned with this wart ruining its appearance but it’s hurts!
