Recurring inflammation of the sinus cavities in the cheek area, forehead and eyes, is classified as chronic sinus infection.
Chronic Sinus Infection Causes
The sinuses are cavities in the nasal bone structure, and 4 distinct types of sinuses connect to the nasal passageway. The sinuses act as the body’s sieve, keeping out dust and similar foreign objects, since the sinuses are part of the nasal passageway. Mucous and nasal fluid is discharged through the sinuses. The symptoms are triggered by allergies and infection, if not an allegy-induced nasal blockage, dental infection and an allergic reaction to fungus.
Although chronic sinus infection does not occur as much as the acute type, its onset may seriously damage sinus tissue. 
The symptoms of chronic sinus infection are common enough, including fatigue, persistent cough, severe headache, facial discomfort, congestion of the nasal passageway and pain in the teeth or roof of the mouth.
To determine a sinusitis diagnosis, the medical practioner might tap the sinuses under the facial skin to examine them, a method called percussion. Percussion reveals any tenderness that might indicate a sinustis infection. The infection can also be diagnosed using tests such as a CT or MRI scan, and x-rays, to show whether thickening of the sinus tissues or fluid excess has occured due to an infection.
A chronic sinus infection may be treated with a course of antibiotics in the case of bacterial infection. The course usually 3 to 4 weeks long. Decongestants come as nasal sprays and tablets. These help to clear the nasal passageway and relieve symptoms of the infection. The patient might also choose an over the counter painkiller.
Chronic sinus infections are fairly easily treatable, however a delay in the treatment can cause the infection to recur and can cause further problems including abscess formation, and risk of the brain, eyes and facial bones catching the infection. The spread of the infection in this manner can result in damage to the eyes or loss of sight.
Always consult your doctor at the onset of chronic sinus infection symptoms. Prolonged stress affects the immune system and even neurological health. The stress also makes the patient blow the nose hard or rub it excessively in an attempt to try and breathe more easily. This only serves to irritate the nose and may cause swelling and bleeding. Try to prevent nasal stress with the use of decongestants before the symptoms become worse, inhale steam 2 to 3 times daily and take plenty of fluids.
Avoid as much as possible any foods that might make the condidtion worse. These might include dairy products, wheat, oranges and processed sugar.
