A number of agents could be responsible for an irritation caused in the nose, throat and eyes, the most common of them being dust and the onset of a cold. Allergies, bronchitis and a common cold can cause all the symptoms you have mentioned. The use of lotions, creams, cosmetics or perfume could also cause irritation in the nose, throat and eyes if you are allergic to some ingredient in it. An itching sensation in the eyes, throat and nose could also be the result of hay fever that is caused by pollen in the air. Air pollution can also lead to a burning sensation in the rear of the throat and nose, due to the existence of chemicals in the air. Breathing in noxious gases and fumes can have similar effects. Tobacco smoke is a well known cause of irritation in the throat and can cause discomfort to the eyes too.
In order to relieve yourself from such a situation, it is necessary to first ascertain the cause of the irritation. Most often, it is something in the environment to which your body has not adjusted, thereby leading to an allergic reaction. Trying to recollect when the irritation started may help you to determine the cause. Once you have pin pointed the aggravating agent, it is time to deal with removing it or protecting yourself against it. Changing the hair care or skin care products that you use may help to reduce the symptoms, if caused by allergens present in these products. Smoking should be avoided to reduce the discomfort. An irritant causing discomfort in the back of the throat and the nose will eventually lead to a release of fluids from the tear ducts present in the eyes. Honey mixed in warm tea may help to relieve this condition to some extent. Lemon juice, rich in vitamin C, is known to fight infections by strengthening the body’s ability to fight infections. Drinking lemon juice with a spoon of honey, diluted in water, will help to build up your immune system.
Since the symptoms you have mentioned are very general in nature and commonly faced by people suffering from different conditions, it is difficult to determine the true cause for your condition. Hence, it is important that you visit an ENT specialist and have a thorough ear, nose and throat check carried out. This would help to ascertain the root cause of the problem and enable you to take proper treatment accordingly.
