Re dizziness after sinus surgery; You have an infection in inner. or middle ear...or Eustachian tube (canal that connects sinus to ear).
You mentioned you were using an irrigation but if me I'd use a strong anti viral//fungal...Colloidal Silver. I've knocked out a number of such infections over the years. Using an ear syringe, squirt into ears and into sinus cavity. Since you just had surgery there do as gently as you now do with the irrigation you currently use. I'd repeat three times daily for three days.
