Around 2004, I started getting sinus infections out of nowhere. As time went on, they increased in frequency and duration. Sometimes I had to be on antibiotics long term to get rid of it. I almost always had a sinus infection. It was a miserable way to live. Fast forward to 2013, I saw an ENT. Last April, I had a septoplasty, turbinectomy, concha bullosa re-section and sinus surgery on my ethmoid and maxillary sinus cavities. While I could breathe better and the sinus infections weren't as bad, I still got them. The doctor told me smoking was probably the culprit. Yeah right, I thought. A couple months later, I quit during a sinus infection. I have had one sinus infection since then, just one. Coincidence? I think not :)
