With eye pain, there may be other symptoms too, which may help diagnose the cause of the discomfort. These include: 1  Conjunctivitis-red itchy eyes. 2  Tears. 3  Light sensitivity (photophobia). 4  Discharge, which can be clear, or thick and coloured (pus). 5  The eye being crusted shut after sleep due to discharge.
The process of breathing performs a number of important gas exchanges through inhalation and exhalation. When someone inhales, they contract and move their diaphragm, which allows the lungs to expand. This is a part of the process needed to psychically suck in the air. When a person exhales, the diaphragm relaxes and the movement is undone. This allows air to be gradually pushed out of the lungs.
But studies show that about 80% of bad breath comes from an oral source. For instance, cavities or gum disease can lead to bad breath, as can tonsils that have trapped food particles; cracked fillings, and less-than-clean dentures. Several internal medical conditions also can cause your breath to go downhill fast. They include diabetes, liver disease, respiratory tract infections, and chronic bronchitis. You'll want to see your doctor to rule out things like acid reflux, postnasal drip, and other causes of chronic dry mouth (xerostomia).
