Welcome! Great advice has already been given.
Just making sure your 100% sure it is a nose rub. Can you share a picture of the temp home and a full body shot? This can always help with semi-diagnosis- vet visit would be more specific. <------- Added that because it seems in some areas vet appointments are taking about 2 and 3 weeks out. We want the best for your little guy. You can always cancel if he gets better with the honey.
I would have a wellness vet visit scheduled just to make sure nothing else is going on. Plus, you will have documentation on weight, growth and health recorded.

No harm in that.
