Well, I've had a dull headache for well over a week now. I'm starting to worry that maybe I have a brain tumor. Its mostly in the front and top of my head, into my eyes. I think its a sinus headache, because people in my department have been sick, but the strange thing is, my nose is not stuffy and I'm not sick in any other way. I've taken some over the counter sinus medication, but it really doesn't do anything. Does anyone have any suggestions, opinions on what might be the problem?
