Hopefully he’ll bounce back straight away. My mare had spasmodic colic years ago, she’d just eaten, stretched out & groaned and immediately broke out in a sweat. Vet was straight out with buscapan and she was right as rain next morning. Never had colic again touch wood.
Glad he is ok. Colic is just awful. I'm so glad your boy is ok.
Shils is also right. When my girl had colic last year she continued to colic through pain relief and 2 lots of buscopan. Turns out she had an impaction at the front of her stomach and needing to be tubed.
