My horse has a sinus infection for the first time (he is 12 years old). My vet wants to skip an antibiotic treatment and go straight to an x-ray of the head (confirm it is a sinus infection with the fluid and check for a tooth problem - if she finds a sinus infection she wants to drill the hole and do the draining, testing the sinuses for the type of bacteria). She feels general antibiotics are usually a waste of time with potential negative side effects for the horse. I don't want to put my horse through all of that if antibiotics might fix the problem. I wanted a second opinion... to see if I should try the general antibiotics first or take my vet's advice and skip to the x-ray.
Have any of you had sinus infections in your horses? Did they respond to antibiotics?
Thanks so much for any advice!
