That depends on the causes.
If it is seasonal symptom(especially when spring comes it gets serious),you may have to pay attention to allergens(such as flower powder) that may induce the irritation, you can just do medical test to find the allergens. And sometimes the water you are using is not clean, you can make confirm of the water's safety by doing a research about your problem around you to find if others in your neighborhood have the same problem as you. Finally, the cosmetics (such as cream, shampoo, etc) you are using can be the cause of your irritation, so you can try to change them timely.
Hope that can help you.
