First, big hugs...
The first thing that came to my mind when I read your description of what happened was thrombi (because of what happened to Tounsi). Did she kick? Did the spasm in her abdomen seem like it could have been voluntary at all? (Can you send me the video?)
Hernia, definitely. Quintus has a median line weakness and some herniation but it seems painless.
I think we're in something different, because what was going on with Quintus was chronic rather than acute, and pretty slow. Never found out what it was but the end of it seemed to coincide with me stopping wet food altogether.
So, Quintus has 50 too. It's the limit of what the machine can read (so it's basically HI, off charts).
About panc: he ate and eats fine all through his horrible SpecfPL values. He was 50 at the worst of it (pre-diabetes) last winter. He came back down to 12 or so. He was back up to 50 last blood tests.
What my vet told me about interpretation for that number: symptoms trump labs. Quintus is asymptomatic, largely, though I've managed to argue he probably has another gallbladder infection. I'm not sure I'd count Asia as asymptomatic if she seems in clear pain.
Now, can panc cause acute pain and spasming? Spasming, if it was as I imagine it to be (rapid?), really makes me think of sharp pain, so gallstones or thrombi? Or a mini-stroke as others suggested?
Could you check back to the US results what was said about the gallbladder? Where there any signs of inflammation around the pancreas?
Also, you know what I think --
don't be afraid of NSAIDs.
More hugs, vines, and crossed fingers and toes.
