Colic

Well we had an interesting day,,, Joey had a bad case of Colic. He was is so much pain it was hard to watch. He was fine in the morning, so I thought. He ate his breakfast then went out and was eating his hay when we left. We were gone about an hour and when we came back he was laying in the overhang near the barn, when I went up to him he got up but was acting a little funny, he started doing circles trying to go down again, he got half way down and I saw his back legs shaking, then he got up and kicked his belly I knew right away something was wrong ,, my husband started to walk him around and wouldn't let him go down, meanwhile I got on the phone to the vet, all the vets that were close to us where out of town at least an hour away, So I called my regular vet who's office is at least an hour away from us, I thought maybe she may be in our area,, Thankful she got to us in about a half an hour. She arrived and right away took vitals,, they were okay, she gave him two needles and some anti-gas,, she said he had a lot of gas on the right side and she was afraid with so much gas that he could tie up ( which is really bad) after he got the needles he started to perk up with more life in his eyes, She stuck around and Don (my husband) walked him, the vet took his vitals again and said he was doing better we fed him a handful of hay and he ate it, for the rest of the day we had to give him anti gas 3 more times and walk him for 10 minutes every hour till 8 that evening. He also got a feed of warm bran mash with mineral oil. The next morning he was doing okay, he had his breakfast and then went right to the hay. Joey still isn't 100 % but he is doing better. I am still worried about him, he's my baby.
Two factors that may have played a role in this.... 1- change in weather- warm to cold and last week I found mold in the hay. We got all our hay for the winter from the same person, we will have check the hay more carefully when we give it the horses. Well I guess that's all for now.
