Having a cold or flu is one of the most common ailments in children and adults, and sometimes these infections of the respiratory tract result in other symptoms attributed to sinus infections. But what are they? The sinuses are empty cavities in the skull. They are located behind the cheekbones and in your forehead, and they are all linked to your nasal cavities. The lining of these cavities have a similar structure than that of your nasal cavities, and they play an important role in modulating the tone of your voice.
Sometimes, the lining of these cavities is colonized by bacteria or viruses, and they start swelling and undergoing secretory changes. These changes characterize sinusitis, and some people might be especially susceptible to having this problem. Sinusitis is not a life-threatening problem, except in very specific conditions, as in untreated chronic sinusitis in small children. However, even if you are not likely to have severe consequences, it is very annoying, affects the quality of life, and even our sleep pattern as you will see in this article. The most important symptoms are as follows:
1) Nasal congestion
It is one of the most common symptoms in sinus infections or sinusitis. Sinus cavities are connected to the nasal cavity, and they are covered by an epithelial lining with mucus-producing cells. Mucus is produced whenever the tissue detects a pathogen and needs to clear it out. In sinus infections, this is what happens in the affected cavities, and as the mucus accumulates, it starts causing congestion when it drains to the nasal cavity. Nasal congestion may also be the result of an underlying problem because in most cases sinus infections start alongside with respiratory infections such as influenza and bronchitis.
