This doesn't look like any case of colic I have seen in 35 years..... unless he just isn't the typical head to side/ tummy kicker/ roller.

If you call just about any vet they should be able to give you some benamine if you cannot get the horse to them and they cannot get to the horse.

Prepare to camp out in the pasture with him all night long.

It's exactly how they act in the beginning stages of colic. They are first off their feed & barley interested in it. They'll lay down & get up often. They'll lay down in the middle of the day & stretch completely out when they normally are grazing. Then get up & stand a few minutes & lay down again.

If the horse is starting to sweat that is a sign the pain is getting worse. And the symptoms you are describing MM1 are when the colic has gotten to the extreme dangerous stages.
