Allergies occur when the immune system of a person reacts or even overreacts to some allergens. Allergens can be any substance, but most of the time, they are like pollen, dust, or it can be even pet dander. The reaction is basically like a negative response by the body to the substance. The immune system reacts to it by releasing substances like histamine.

Sinus infection does not require a stage or time to happen. It simply happens when the nasal passage becomes inflamed. Most of the time, the sinus infection is caused by an external virus. When this happens, the nasal cavity inflames, and the mucus builds up even more and gets stuck, and this further elaborates the problem even more.
