My filly has a stuffy nose?

[Foster Woods Miniatures]

When I first got her she had pneumonia, but we cleared her of that. Now she is having a constant snotty nose, but it doesn't seem to be getting in her way! We called the vet, worried that it may still be the crud, and she was perscribed something, i dont remember the name. But her nose is still stuffed! its not draining.. im wondering maybe its allergies? Any input? Thanks!

As she has had pneumonia I would say this would warrant a visit to the vet, just to make sure. If its truely allergies i have heard that spirulena is a good natural remedy but have not tried it. I do have one pen of my young boys that seem to get a snotty nose every year, and the vet finds nothing wrong with them. My farrier suggested to try some apple cider vinegar (unfiltered and non pasturized) it has worked two years in a row now. I have no idea why though...
