Bleeding from nostril--Thanks!

[mtnridr@pacbell.net]

Many thanks to all who replied to my question regarding bleeding 
from a nostril during a ride.  Looks like the possibilities include 
foxtails, stress, guttural pouch infection, dry weather, fungus, 
tumor, exercise-induced pulmonary hemorrhage, or (my personal 
favorite and the one I'm hoping applies) nothing at all.  I do 
appreciate having this board as a resource and reaping the benefits 
of your experience.  

As far as my husband's horse goes, we have been on the trail 
several times since I posted my question and have had no further 
episodes of bleeding.  I've been checking his nose at various points 
in the ride to see if I can spot when it starts (like after a hill, 
canter, etc.)  A journey starts with a single step, and so we will be 
playing it by ear and keeping a careful eye on things.  If another 
significant episode occurs, we'll be getting the vet out to scope.

Again, thanks, everybody!
