ELI5 : Why can't internal organs be itchy?

If internal organs can hurt, why can't they get itchy?

I think the body would evolve to discourage that.  The only way to scratch that kind of itch is going to harm you. 

Consider the reason for an itch evolved in the first place... it's to get you to brush off bugs and other critters. And for this it's better to have false positives.  But bugs don't tend to get inside you.  And if they do,  no amount of scratching is going to help.
