Allergies
Sinus headaches can be caused by allergies. Some common triggers include foods, smoke, dust, mold, pollen, and other elements. A headache is often a response of the body against these triggers. It is important to notice your symptoms and inform your doctor to rule out the possible cause. Keep in mind that some medications can also lead to a sinus headache due to an allergic reaction. Some lifestyle changes can be effective in preventing allergies, thus minimizing the frequency and intensity of sinus headaches. [5]
