Worried about pied turning pink.

I know some pieds or bels can turn pinkish before a shed but my boy never has. Is that what this is? Or something else? Maybe something to be concerned about?

That does not look like shed pink to me. Shed pink usually shows up as an even salmon pink.

To me this looks more like some kind of injury but I can't say for sure. Someone with more expertise will probably have a better answer.

One of my snakes had signs of a very minor uri yesterday(being treated as we speak). Because of this I checked all my snakes, he was the only one that had a bit of a freak out, didn't hit anything at all or recieve any injuries but he squeezed onto me extremely tight, EXTREMELY tight. Could that of caused that?

No other cases of uti in any of my snakes except the one.
