I might be paranoid, but...?

Alright, I know I just answered another question about "crooked" legs so maybe it's stupid to post this...but I'm a little paranoid. My yearling gelding has very nice conformation, but I've noticed that something looks "off" about his front legs. He doesn't appear affected because he moves fine and isn't lame. But when he was 3 months old a witchy mare we were boarding went after him, and his only option to get away was to either go through the fence or jump the water trough...luckily he chose the trough...but he landed with his front feet out and his hind legs in. He was fine...no cuts or scs, and no lameness, so we just kept an eye on him for any changes. Well like a week later, he started acting stiff and would tip toe around..we asked the vet as there were no visible signs to why he would be lame (his feet weren't hot either)...and he said that maybe he had a metabolic disturbance that needed to work its way through, and it was affecting his hoof growth...(continued)
