Im not judging, im just informing you what is likely a very stressful situation for your animal. Why dont you buy the rat mouse whatever on your break and take it home with you and feed him there. You still did not answer the questions about the heat, which could be the cause of the scale rot or possible a burn. I too work long hours, up at 4am, drive an hour to work, till about 1800, drive an hour home, I have 10 BP to care for every evening, and a rat colony, and a monitor, and a cat. If you dont have time for your animals maybe you shouldnt have them. You also keep ignoring the suggestion to take him to a vet. They can give you proper advice, and will give you antibiotics that he will likely need to prevent infection if there is not one already.
