Big bubble on fawns nose/snout

Hi!  I love this site.  Here is my short story:  I just became involved with deer rescue after finding an abandoned whitetail fawn almost dead.  I know a few DNR and Animal Rescue people, so I was able to get involved as an assistant and am permitted to raise/release this little buck fawn.  This is all new to me, but has been going very well.  'Buck Rogers' is about 3 weeks old and bottle feeding, eating dirt and leaves on his own, following me around the yard like a puppy.  I put up a 20x30 pen where he spends the day hours, and at night he still sleeps in the garage.  At any rate, yesterday I noticed a grape sized bubble on his nose/snout.  I am guessing it's a bee sting, but really have no idea.  It's been 24 hours and hasn't changed.  He seems to be fine, but I wanted to ask if anyone has seen this?  


Thank you,


Kurt


 

I did a search and found a post entitled "

Bump on Doe Fawns Nose    


The topic wasn't finished but I wonder if it's the same thing?

Thank you!

Ok, it's been 10 days now and no change.  It looks like somebody shoved a grape up his nose.  Doesn't seem to be causing a problem but do I need to do something?
