Looking for opinions: Monitor skin torn off?

Hello everyone! I noticed today that my ackie monitor seems to be missing skin on a small part of his tail. I have put some Curad silver solution on it to prevent it from getting infected. The curious part for me is that there is no blood. I plan on taking him to a vet unless this seems like a minor issue? I have a feeling my vet would prescribe the same thing with the silver cream. Can I get any thoughts as to what caused this? Does it seem like he has stuck shed or other issues? He seems incredibly healthy, eats like a monster on dubias, crickets, and the rare hornworm or pinky mouse. Temps are 140-150 F on the hot spot, 90-ish on the warm side to 80s on the cool side. About 5-6 inches of dirt for burrowing (until he gets bigger where I will be adding the rest of the 6 inches) and lots of branches and wood to hide and climb on. Fresh water always available. Attached are pictures of the affected area.
