Sinus cavities are cavities in the head which are connected to the nose. They are filled with air. Sinus cavities are of four types they are the maxillary sinuses, the frontal sinuses, the ethmoid and the sphenoid sinuses. These sinuses are very prone to infections or allergies. A mucous filled sinus is very fertile for bacteria to breed. A viral infection can also cause sinus as it causes the sinus membranes to swell. Sinus symptoms vary from time to time depending on the duration of the attack. Sinusitis is more common during winters as compared to summers.
A typical sinus attack lasts over about two to three weeks. Initially, it appears to be just another common cold. With the passage of time, the symptoms of sinus are seen or felt. Acute sinus can also lead to several complications which can be a threat to the patient's life. Sinus should be treated as soon as possible.
One of the most common sinus symptoms is a long term cold which does not respond to conventional medication which is given for a common cold. A persistent cold, slight headache in the morning and low grade fever are other common symptoms.
Sinus patients also feel weak due to over exertion. They also have a perpetual runny nose and congestion.
Sinus symptoms may also depend on which one of the sinus cavities are affected. Some patients complain of pain in the head and on the side of their nose. Some complain of pain in the upper teeth which increases when the person bends down. Pain in the entire face and a slight swelling is also observed when more than one cavity is affected.
However, the most sure shot and the most common symptom of sinusitis is nasal discharge and pus in the nasal cavity. The discharge is yellowish green in colour and is full of pus.
Some people also have chronic sinusitis. Such people complain of sinus symptoms very often. Their colds stay forever. They complain of nausea and fever. Such people have chronic sinus. This is most common in people who have asthma or other allergic disorders.
It is recommended that those who have sinus symptoms should start medication as early as possible.
