Sinusitis

There are times when you wake up with a cold, you feel tired all day your cough never seems to go away. Even laughing hurts at times because the whole face aches if you have such symptoms, it is very important to understand what sinus disease is. Sinus disease is the inflammation of the lining of the sinus cavities present in the skull. Sinus cavities which are normally air filled, become filled with mucous due to lack of proper drainage through the nasal passage. This inflammation could be due to viral or bacterial infection. Allergies could also cause this disease.
