Are neti pots effective for chronic sinusitis? ive tried all kinds of sprays and oral medications but nothing works only this is left. also dont know what has caused this long term problem. so i visit an allergist too?

Sinusitis can be a chronic problem. Small changes in hydration and wellness can cause a flareup of the symptoms. Inflammation can frequently cause secondary infections when fluid builds up and allows bacteria/viruses to grow. Use saline nasal washes daily, combined with decongestants, antihistamines and if infected, see a Dr for Antibiotics. Regular prevention = avoid symptoms.
