I have had sinus surgery and get allery shots. Now, I watch other people suffer the way I used to. My symptoms are still there but very minor. It is certainly worth checking into the shots. When I had the surgery, I could hardly breath out of my nose at all and the during the surgery to fix a deviated septim (sp?), they removed two csyts. The surgery and recovery were bad but worth it. I hope you have gotten an mri to determine a course of action.
