Where are the sinuses?

The sinuses are located within the middle part of the face. They are paired structures and there are 4 main groups- a pair beneath the eyes, a pair between the eyes, a pair above the eyes and the last pair located toward the back of the nose. There are many different problems that may arise from the sinuses. For example, sinus problems are associated with nasal blockage, problems with the sense of smell, facial pains, runny noses and mucus running down the back of the throat.

What causes sinus problems?

There are in fact about 12 main categories of problems that contribute to sinus problems and then there are several different contributing factors that are classified within each of these categories. Given that each person may have several different contributing causes to their sinus problems, you can see why there is no "one cure fixes all".
