Thanks so much everyone! Last night he wasn't doing too well. Had a temperature and wasn't eating. But, one of the girls at the barn gave him a shot for the fever and also gave him an alcohol bath. He was also getting dehydrated because he wasn't drinking water. So, I had to go to the store and get some apple juice. We wet down his food and then put the apple juice in it and he loved it! So, now he's eating and drinking and the swelling has gone down a little. He was his old ornery self today. Pawing the ground getting impatient. I'm so glad he's feeling better. Was very worried about him. Thanks for everyone's concern.
