Has anyone had experience with bilateral sinusitis in horses? Im trying to find anything I can to help a filly I just saved from the sale barn yesterday. I know she had retained baby caps that were pulled by a vet but the previous owner didn't do any follow up care so this is what she looks like today. Anyone have any ideas on oils to help her. She has been diagnosed by a licensed veterinarian and is being treated by them. I'm just looking for any ideas on what I can supplement the vet care with.
