I'm really glad the swelling has gone down. It's really scary when we know something is wrong with our babies and can't be there to see or help them. Luckily mine are in a place that I can go to anytime. When Rose had her surgery, the BO actually offered to let me stay in thier house so I could go down and check on her periodically instead of having me driving out every couple of hours or staying there in my trailer. If it is an allergy, maybe you can see if the vet can give you something to help. I have a couple of friends who have their horses on daily allergy supplements. GOOD LUCK!!!!!!!
