A member asked:

Does latest research now say that chronic sinusitis is caused by immunity or allergy problems rather than by improperly treated acute sinusitis?

Chronic Sinusitis: Chronic sinusitis is a multifactorial problem including anatomy, physiology, immunology etc. The contribution of allergy and immunology are well established and not new (thats why you are on steroid spray). Sinusitis is not always a bacterial infection of retained mucus in a sinus. It may be due to atypical organism such as fungus or just Osteitis. Only an experienced ENT can properly treat it.
