There are times that one would wake up in the morning and notice some swelling around their eyes. This could also be accompanied by feelings of being stuffy and severe headaches. Most probably, one is suffering from sinusitis. Sinusitis is the medical term used to refer to the inflammation and swelling of the sinuses, which are the air spaces that are located on the face and around the nose. This is mainly caused by a variety of infections that have also been held responsible for causing swelling and irritation of the sinusitis. This disease has been linked with an interference with the way one voice sounds. It is attributed to a virus that causes the infection of the sinusitis. Although this disease is painful and irritating at times, doctors and other health specialists have noted that, it is less severe as compared to other types of diseases that have been attacking man since time immemorial. Nevertheless, this doesn't mean that it deserves to be given less medical attention, than other types of diseases. In fact, doctors have maintained that, upon noting its first symptoms, one should seek medical attention. Failure to this will lead to more problems, thanks to the irritation that will be responsible for making one feel uncomfortable all the time.
