I just have to say thank you to all of you for being civil with this. I posted one of the pictures on a local facebook group just to see if people in my area have had the same bulge on the toes. Many did and said it was just the sole growing weird, which in my case I doubt that, but then I got attacked by a barefoot trimmer for ever having shoes on this horse. And the suggestion was that I shouldn't ride her since her soles are thin but shoes are too bad.
So thanks for actually explaining things and giving helpful suggestions, it is refreshing to know people can help without starting a debate.
