The lining of my right sinus is completely destroyed. My most recent flare was all sinus, nothing else. My migraine headaches were from my sinuses, which my ENT described as "looking like a kids scraped knee when he fell off his bike." I do have a perforation in my septum, small, but there. My left side isn't as bad as the right but the lining is still damaged. Both are slowly starting to recover, but still take a good cleaning by the ENT every two weeks to keep the crusts under control.
I've moved form the bottles to a Waterpik and run 3 liters of saline through my sinuses twice a day with it. That is the single best thing I've done in the past two years is running the oodles of saline through. ENT can't believe that I have kept that rinsing regiment.
