I m having flu symptoms with a type of headache that I have only experience when having the flu. I m getting steady, consistent flashes of pain the pain on the right side of my head, but when it comes it gives the feeling of tightening a band around my head. Since I feel like I have the flu I am drinking extra water, orange juice, getting lots of rest and eating some garlic to help me get better faster. I ve been taking bayer for the headache, but I am worried because when I had the flu before a few years ago and I had this seem headache it got really bad, like torture. So far it is mild, but slowly getting worse. I have been sick for four days.
