A tiny bit of Neosporin rubbed gently into the skin would probably be greatly appreciated. The Neosporin is a triple antibiotic ointment that will help combat any germs/bacteria that might be in/on any irritated or dry area of the skin. It will also help hold in natural moisture of the skin.
Remember: When a bone is healing, or an area has been immobilized even for a few days, the muscles will atrophy a bit and it will be painful for the little one to walk on for the first few days. But, as the muscle rebuilds, the pain eases. { I'll never forget when I got my cast off my leg and was able to bend the knee for the first time in a while. My doctor warned me I might not be as happy after bending it the first time, as he gently and slowly bent it ... he was very much correct! It took a while, but was worth it.

Emergency visits to a vet hospital are the same as emergency visits to a human hospital. The human emergency room visit is usually $500 to $1,000 ... if nothing major is wrong ... while the regular doctor's office visit for the same thing would normally be $45 to $80 for the same problem. So it is for animal hospitals also.
This is why I often insisted a person set up a savings account or piggy bank, solely for their chinchilla, with a minimum of $200 in it before they could adopt one of my little ones. Some thought it a bit much to ask, but those who needed it later on, sent me a "thank-you" note, because they would have not been prepaired otherwise.
