Was just going to say this. Try loading him up in the lorry and see if that shifts anything.Really sorry to read this, & am afraid I don't really have anything to add but didn't want to read & run.
If he's comfortable, what about a longer walk with plenty of grass or could he be turned out for a hour or two? I remember an old horseman telling me that he'd got a horse to poo by getting it ready to travel with boots & a rug & loading it on the lorry, apparently the excitement of going somewhere did the trick.
I will be sending lots of vibes, hope he recovers.
OP don't feel you are letting your horse down because you can't afford surgery. I could afford it and still wouldn't put my horse through it.
