Urgent Advice Please - Grey Tree Frog has Hurt Himself!

[Jayzie Greenfrog]

Hi,
i am desperately looking for advice how to help one of my young frogs who has managed to damaged (looks like a graze or he has bashed it) the very tip of his nose.



I am sorry it isnt a very good pic but you can just see the pink tip! Is there anything I can do or does he need the vet our big problem is the only exotic vet is in the next town a very long and expensive taxi ride away I am unable to get there today but it may be possible tomorrow is there anything I can do to ease his pain in the meantime?? I have already lost two cats this month I really don't need to start loosing frogs too!
