Hi. In the last week I've had something like a flu. Sore throat, hurts to swallow, all my joints ache, i have a stuffy nose most of the time, and a slight tickle in my throat (gets worse when I'm trying to sleep). But recently whenever I stand or change positions sitting my head hurts, like a throbbing in the front of my head. I'd really like to know what this throbbing might be, or if i should go to my doctor for testing of some sort.
