Hey, I have been having a headache now for going on 6 days straight. Now, I get headaches quite a bit, and get migraines as well, but I don't think I've ever had one that lasted this long. I can't figure out what kind of headache it is either. It's not really the same as my migraines, but it doesn't seem to be sinus-related either, because when I do get a sinus headache, sudafed usually helps it tremendously. This time it hasn't helped it one bit. I am just wondering if anyone has any ideas, or if it's something I should be concerned about?? I guess if it lasts too many more days, I'll go ahead and call the doctor. I've never had any kind of MRIs or tests or anything done, but I just can't figure out this headache....it's a PAIN!!!
