My 14 year old gelding has a swollen back hmmm I suppose it would be called the fetlock? I left him for a week but doesnt seem to have made a difference so I rode him lightly with alot of walking, some troting and alittle canter. He seemed fine and it doesnt feel hot, he will me touch it. I don't think it's worth calling the vet but does anyone know what it could be? Oh and he grazes in a large paddock.with two other horses.
