Avoid substances which might be giving you allergies. Decayed teeth, enlarged and infected adenoids, cigarette smoke, perfume, household cleansers, and dusty air can cause irritation to the sinuses. So sinus trouble can either be caused by an infection or by other things. If drainage is clear and there are no accompanying symptoms of a common cold, you probably have an allergy. If left untreated, this can lead to bronchitis, asthma, throat infection, or pneumonia.
Maxillary sinuses makes pain in the upper teeth and cheek, and sometimes eye pain as well.
It generally lasts from 11 a.m. to 6 p.m. Ethmoid sinuses induce a dull pain behind the eyes, pain in eye movements, tearing, light sensitivity, and occasionally sore throat and nighttime cough. Do not suppress a cold, flu, sore throat, infected tonsils, or other acute disease. Go to bed, take juices and light meals, rest, and get well. When suppressed, the phlegm does not flow out, but hardens in the sinuses and trouble begins. Take a short fast on citrus juices, vegetable juices, and herb teas.
