Hi there. I seem to be getting headaches every day around the same time, 5-6pm. They last the remainder of the evening, &sometimes they are still present when I open my eyes from sleeping in the morning. I usually take 800 mg ibuprofin with little to no relief. They are in the same spot, as well...my brow bones. Sometimes it is both but others times, it is just one side. It seems to feel like a sinus headache, but I haven't had any cold symptoms nor have had problems with having allergies. Should I be concerned?
