A few weeks ago I noticed a little, hard bump on Jerry's pastern. Not his cannon bone, his pastern. I felt it, poked it, squeezed it, and he didn't even flinch, so it doesn't hurt him. It's not swollen or hot. It has hair on and around it except for a small spot where his skin is showing in the center. It is about the size of a dime in diameter. He has been working fine for the past few weeks, and he doesn't limp or anything.
Is it a splint, or something else?
Could it just be something from an old injury that just didn't go away?
What do you think it is?
