My 9yr old gelding has a hard lump on the inside of his right ankle. He had injured this leg when he was young and, for most of his life, has had this lump. However, it seems to me it has gotten bigger. I could just be imagining things though. I've had a few people tell me it is nothing to worry about since I am not going to do any heavy work with him, but I am curious as to what it is. I'm going to have another vet out when his shots are due to check it out as well. Has anyone seen anything like this? (picture below)
He has alway been a little unbalanced in one direction. We've been working on this in lessons. Though I can't help but wonder if training is not the only reason.
