I know how scary it is to have a horse colicing like that! I had a mare colic at a show and she also almost required surgery. Luckily she passed it after about 72 grueling hours. I hope Nelson pulls through as well!!
My thoughts are with you tonight!
I just got done talking to you, but wanted to say it again. Stay strong Kim. Nelson needs you to be strong right now. He is a big strong boy, and if any pony can do it, it's Nelson. Like we discussed, if surgery is necessary, you have my cell. Call me, text me, anything. Give me an address for the vet and I will do my very best to make sure it's taken care of. Sending prayers to both of you.
