We have a concoction our family uses that is called “Sinus Remedy”
Into glass jar put 1 Cup apple cider vinegar,then 1 teaspoon each:
chopped fresh garlic
chopped dried cayenne
chopped fresh ginger
chopped fresh horseradish
chopped fresh onion
chopped fresh parsley
Let sit overnight; use 1 teaspoon (or more) in hot water or herbal tea. You can adjust according to available ingredients, but best if you have all. My daughter says it’s better than any medication you can get.
Chronic rhinosinusitis represents a multifactorial inflammatory disorder, rather than simply a persistent bacterial infection.  The medical management of chronic rhinosinusitis is now focused upon controlling the inflammation that predisposes patients to obstruction, reducing the incidence of infections. However, all forms of chronic rhinosinusitis are associated with impaired sinus drainage and secondary bacterial infections. Most individuals require initial antibiotics to clear any infection and intermittently afterwards to treat acute exacerbations of chronic rhinosinusitis.
The goal of sinus surgery whether it is performed endoscopically or via balloon sinuplasty is to make the small drainage openings of the sinuses into the nose larger. That's it! By making the sinus openings big enough, the sinuses can't get obstructed as easily and therefore allow for good sinus drainage no matter how much swelling or inflammation may be present. Good sinus drainage prevents/minimizes sinus infections. Paradoxically however, sinus surgery may make your allergy symptoms worse (easier for allergens to gain access into your nose and sinuses since things are opened up), so it's very important to get your allergies under good control before sinus surgery is performed. For those with asthma, having sinus surgery has been shown to markedly improve lung function resulting in decreased number of asthma attacks and use of inhalers overall.
