I finally beat the sinusitis death loop at >50. Key for prevention is:

- keep your mucus membranes moist. Use an air humifier. Orange oil nose spray also helps, or salt water spray

- use a "node shower" after any day with in-person interaction

- wash hands after shaking hands

Key to recovery:

- suppress the symptoms by all means. Your nose HAS TO BE breathing freely. You get exhausted from breathing against a resistance. You also sweat, then freeze in your wet clothes.

- Sleep. Not just lie in bed with a screen. SLEEP

- make sure you're not low on zinc. Take supplements (A-Zinc is pretty good)
