The sinuses are small cavities in the skull that are normally filled with air. They produce mucus, which helps keep the nasal passages clear of allergens and pollutants. Sinusitis is an inflammation of the tissue that lines these cavities. In some cases, this swelling blocks off the sinuses, trapping mucus and air inside them If you have sinusitis symptoms for more than a couple of days, check in with your doctor.With a good exam -- and sometimes imaging tests, like X-rays, CT scans, or MRIs -- you may be able to figure out exactly what s causing the problem. Often, the best sinusitis treatment is a combination of different approaches typically medication combined with self-care. The goal of treating chronic sinusitis is to: 1.Reduce sinus inflammation 2.Keep your nasal passages draining 3.Eliminate the underlying cause 4.Reduce the number of sinusitis flare-ups you have Treatments to relieve symptoms 1. Saline nasal irrigation 2. Nasal corticosteroids 3. Decongestants 4. Antibiotics if it is due to infection 5. Analgesics for the pain Surgery In cases that continue to resist treatment or medication, endoscopic sinus surgery may be an option. For this procedure, the doctor uses an endoscope, a thin, flexible tube with an attached light, to explore your sinus passages Feel free to ask if you have any other doubts Regards
