For sure, this is your horse and you KNOW your horse from top to bottom and the vet wants to "think" it could be something else? That could be the call that changed your horses life forever!
Hope the farrier is more educated! If he see's any signs I would call that vet back and get some anti inflammatory and then put your foot up her rear end after I picked up the script! Wow.. Whats her number I will chew her face off for being so ignorant!
