Sinus Infection
Headaches caused by a sinus infection is not common. Most cases are just migraines followed by sinus signs. So, if you are experiencing recurrent headaches in the facial or sinus area, it is likely to be a tension headache or migraine. Though both sinus infections and migraines trigger pain while you are bending forward, the former does not come with vomiting, sensitivity to light, or nausea. Instead, it is often characterized by phlegm or fever. If a sinus infection is the cause of your headaches, then antibiotics can be an effective option to treat it. [9]
