I have Vertigo. Had a sinus surgery to remove blockage on both right and left passage. Surgery was 8/4/2016. The vertigo set in suddenly on 10/4/2016. Been diagnosed as the Viral type. I am rinsing sinuses regularly, today, 01/24/2017, still getting some blood in the mucus discharge. Normal? Coincidence of surgery, then vertigo? Have gone thru PT to assist motor skills, slow progress. Help?
