What do yall do for Sinus Inflammation?

Hey guys, I clench at night, got a guard and everything, but Ive been told my left sinus is inflammed by both an ENT and a Dentist. This makes sense, because I have tons of horrid ear problems on only my left side. Not sure which came first, the sinusitis or the TMJ. After all my research and treatments over the past 4 months things have gotten better recently with my ear issues, and I feel like if I could kill off this sinus inflammation I could get to an 80% recovery from everything. 🙏

Wanted to know what are some effective remedies that you've used to manage or decrase sinus inflammation?
