Yellow scales after shedding

[Camden17]

So two days ago my bearded dragon shed the bottom of his tail and it looked like he had some blood underneath the scales and he flinched when I touched it, so I added some honey to see what it would do. Now the blood is gone but his scales there have a yellow tint. The top of his tail is unshed so I am thinking maybe the bottom shedding came off early, but would that cause it to turn yellow?

Does anyone know? Should I take him to the vet?

To me it looks like it was maybe pinched in something. Is there anyway that was possible? I don't know too much about tail rot but I would look out for signs of infection.
