So last year my Affenpinscher had to have his spleen removed due a benign mass.

As you can see I was not certain it was the best thing to go ahead with the operation but the vet I trust said if it was his dog he would. All went well, the mass was benign and he recovered surprisingly quickly.
Here we are a year later, he's 15 now, and he has started acting strangely after eating, about half an hour after being fed he acts very stressed, like he used to act with fireworks, so unable to settle, pacing, pawing at us. This goes on for an hour or two then passes. So I'm presuming discomfort caused by eating.
He's fed raw complete so I tried chicken & rice which upset his tummy so I did a 24 hour fast and he was fine but as soon as we fed him again the symptoms came back. He is still very keen to eat, is drinking, weeing & pooing fine, no vomiting.
Obviously I'll be ringing the vet tomorrow but I just wondered if anyone out there has experience of this or any idea what it could be?
