Ouch. I'm getting over a fairly similar thing, though the cold itself was fairly mild, the sinus component was KILLER. I developed a headache Monday night and only in the past hour or two has it seemed to have more or less stopped hurting. I got lots of fluids, napped, drank this home remedy (http://www.earthclinic.com/Remedies/tomato_tea.html), and took a dose of Mucinex D.

Hope you feel better soon! *hugs*
