Headache
Did you know that there is something called a “flu headache”? Because of vomiting, gastrointestinal issues, muscle aches, fever and chills, and other symptoms, you might also develop a headache that makes you sensitive to sounds and light.
Individuals who are at risk of tension headaches and migraines are also at increased risk of flu headaches. When the mucus membranes lining the sinus and nasal cavities become inflamed, it increases pressure inside the head. As a result, your headaches may feel stronger.
