I had sinus problems for many years...every year at season allergy time. I had migraines two to three times a week. I ended up have sinus surgery over 10 years ago and probably have had five headaches since the surgery. You will need to see an ENT doctor. The process took 45 minutes from the moment I walked in the door. I'd liken the process to getting a cavity filled. Here's a link describing the process. https://www.healthline.com/health/balloon-sinuplasty
