Hi, Dave --
 
I've been following your messages about your sick horse.  Like some of the 
others here, I'm curious about the fact that his nose is running and whatnot 
only on the one side.
 
This is just a wild guess, but I wonder if some foreign body has gotten 
trapped in his nostril and is obstructing/irritating his nasal passage. Or if 
he has some sort of abcess, maybe this would account for the discharge.
 
I'm also wondering if you might not have two completely separate problems 
going here, neither of which have been diagnosed because they only usually 
present a subset of the symptoms your horse is showing.
 
Also, I read an article a while ago about how some treatments for respiratory 
treatments like asthma (in humans) can set people up for problems with 
parasites, which produce asthma-like symptoms, and round and round they go.  
If I remember right, the long-term use of steroids mucks about with the 
immune system and makes a dandy enviroment for worms to take over.  Could 
this be some sort of parasite-related thing?
 
I'm sorry to post such a bozo-like set of speculations, but if you can rule 
out the ordinary causes of symptoms like this, then maybe something else is 
going on.
 
Overall, the cough and one-sided discharge plus labored breathing really puts 
me in mind of other cases I've read about where an animal has something 
(usually a food particle) physically obstructing the airway.  But I wouldn't 
expect that to go on for as long as you've said, so that would point to 
something else like a tumor or persistent infection or some kind of abcess.  
I think you said he wasn't running a fever, but if he had a chronic low-grade 
infection, it might not be enough to trigger the kind of defense mechanism.
 
Whatever it is, I hope you can find out the cause and you have a good 
outcome.  Good luck.
