Itchiness under left ribcage

A few months ago I began to have an itchiness that began to occur, usually after eating on or under my left rib cage only. There are no other symptoms. No rash, no redness at all, no other skin changes. It's just annoying at this point, but I wanted to check if anyone knows why this may occur. Could it be my kidney's

I don't eat seafood. I've seen a others complaints after eating raw fish, but that's not an option in my case .

Any ideas Thanks for your help.
