What causes sinus headaches and sinus pain?
As I noted before, you can get sinus headaches and pain from having a cold or flu, but the purpose of this article is to address chronic sinus headaches and pain. Chronic sinus headaches usually are typically caused by allergies. Common allergens are mold, dust, pollen, and food. The direct reason for sinus headaches and pain is the actual inflammation and swelling of the tissue in your sinus cavities which can be caused by allergic reactions. This inflammation and swelling does not allow your sinus to function and drain properly, thus leading to congestion and pain. In my particular case, the source of the allergies was two-fold, pollen and mold. Now the kicker here is that the mold allergy was not airbone, it was food ingested, which took me quite a while to figure out.
