Symptoms and causes of sinus infections - Part one
People usually think of a cold when having those regular symptoms; hardly when the headaches become unbearable they see a doctor and find out they suffer from sinusitis. Although sinusitis only means an inflammation of the sinus cavities, the symptoms are always worse than you expect and people spend millions every year trying to relief the symptoms.
Sinuses are small air cavities located around the nose, known as Para nasal sinuses, situated inside the head bones. The frontal sinus lies right up the eyes in the brow area, the maxillary sinuses are inside the cheekbones, the ethmoid sinus is localized between the eyes and behind it, and the sphenoid sinus lies behind the eyes in the upper region.
Every sinus cavity is connected with the nasal passages through a membrane layer which can get inflamed, and with the nose for air and mucus exchange. Inflammation together with sinus obstruction and secretions blocked inside the sinuses lead to an increased pressure and to the apparition of powerful headaches. Sinus attacks can also be caused by the swollen membrane that blocks air from going into the air passages.
Sinusitis pains have different characteristics depending on the involved sinus; a general type of pain is the one coming up in the morning when you get off bed. Aches caused by bending the head forward are specific for frontal sinusitis; pains in the upper teeth, upper maxilla and cheeks are signs for maxillary sinus infection. The ethmoidal sinusitis causes pain between the eyes and swollen eyelids, loss of the smell and airless nose. Sphenoid sinus infection is a more rare condition and gives deeper pains in the head, earaches and pain in the neck.
General symptoms of sinus inflammation are:
2. Nasal congestion or runny nose
3. Loss of physical strength
4. Bad cough attacks especially at night
5. Larynx irritation because of the mucus drainage to the back of the throat
Bacteria and viruses entering the nasal passages with the breathe air cause most of sinusitis cases. The human body reacts against colds and flues caused by these organisms by secreting a higher quantity of mucus which will eventually be trapped inside the sinus cavities together with air. Immunity cells called leucocytes get there firs and cause the nasal congestion and the swelling of the membrane lining. When the nasal passages are blocked, infection develops as bacteria specific to the respiratory tract multiply and become destructive.
Viruses, bacteria and fungus colonize our bodies without harming them. When the body is weaken and in our case, sinuses are blocked, they become aggressive and can produce acute sinusitis.
