Mites Question about piggy mites

So, based on the wonderful information that I have read on these forums, I have come to the conclusion that my piggie, Albus, has mites. He has scratched the back of his left ear raw. I am ordering Ivermectin "pour on" online for him, but it will be a few days before it gets here. (the only place around here that sells it is Tractor Supply, and it comes in paste form). My question is: In the meantime, is there anything I can do to make him more comfortable? Is there anything I can put on his ear to make it feel better? Neosporin, or something like that?

Thanks in advance for any advice!
