Dealing with this right now. Have a pretty severe sinus infection (deviated septum and bone spurs) that my ENT is pushing surgery for- while google is full of people saying surgery should be a last resort. Now I’m not sure about anything!
It helped me a lot at first with relieving pressure in my sinuses but after about 5 years the benefits are not as strong. I would still recommend it if you have severe problems with headaches and sinus pressure. The recovery is quite painful for a few days. The meds they gave me barely touched the pain but I healed up pretty quickly
