Sick again

I don't know it is ...but I'm down with a flu again. This time, a horrible sore throat and a headache that makes me feel like my head's gonna explode. I've been on painkillers but if it persists, I think we'll have to go to the doc's. I've been drinking lots of water and sleeping as much as I possibly can (with a 11-month-old who's an extremely light sleeper and poor napper). But I just don't seem to be getting any better.
