Sinus is a hollow air space anywhere in the body. There are four sets of sinus attack referred to us paranasal sinuses. Each of these sinuses opens into the nose and shares a continuous mucous membrane with it. Because the nose and sinuses are so closely connected, a viral  or bacterial infection in the nose can spread easily into a sinus. The resulting inflammation of the sinus mucous membrane is called sinusitis, or a sinus attack. A cold, influenza, allergies, a tooth or throat infection, can all cause sinusities.

The symptoms of sinusitis include nasal blockage that becomes worse after a few days instead of better, as with a common cold; a thick yellow and green discharge from the nose; and depending on which sinuses are effected, pain in the forehead, cheeks or around the eyes. Eventually the passages between the nose and the sinuses may become completely blocked; this may reduce the discharge but makes the nose feel even more stuffed up, and breathing has no to be through the mouth.

SINUS HEADACHES
Before using sinuses drained,  try a humidifier or vaporiser to offset the drying effects of heated winter air. Applying hot wet compresses or heating pads to your nose and forehead may also help. Don’t blow your nose with excessive force, avoid smoking and alcohol, and take aspirin or paracetamol for your headache pain.

If these measures don’t work, consult your doctor. He may prescribe an antibiotic if an infection is the cause of your sinusitis, or an antihistamine, if an allergy is the cause. Or he may suggest nasal decongestant tablets, drops or sprays. If your condition persists, draining may be indicated. This procedure, performed under local anesthetic, involves creating a new passageway between the nose and the sinus, and either irrigating the sinus or syringing out accumulated mucus with a vacuum device.
