For about two years I had shifting sinus pressure along with drainage down my throat. I consulted an E N T professional and underwent a balloon sinuplasty surgery in my left frontal sinus, as well as a deviated septum correction. It's been over a month and I definitely notice improvements but it still has inflammation and I can't breath out of one side of my nose at any given time due to it cycling back and forth. I need serious advice from any medical doctors out there, my question "What can be causing this swelling and inability to breath and how can I get rid of it or at least reduce it?". I really appreciate all responses, this problem is interfering with a lot of aspects of my life.
