Sinusitis occurs when the sinuses swell and is most often caused by infection or allergy. Most sinusitis is easily cleared up within 2 weeks, and so it is only ratable if it is chronic. Sinusitis can occur in each of the different sinuses or in all at the same time (“pansinusitis”). Treatments range from medication to surgery.
