This is a case of allergic sinusitis or sinus infection due to exposure to any allergen products as cosmetics or perfumes or dust or pollens or pathogens. Allergic sinusitis causes sneezing, runny nose, nasal congestion. When sinuses get inflamed -- usually because of an allergic reaction or an infection -- they swell, make more mucus, and the channels that drain them can get blocked. The build-up of pressure in these sinuses causes pain that feels like a headache. In this kind of situation, a patient feels dullness and lack of energy.
