I may have a flu

Or it could be allergies coupled with back problems. All I know is that I've had post-nasal drip all week and today I had a sore throat, all-over headache, upper backache and a not-right stomach (no nausea, though). It could be allergies and the fact that my tummy doesn't like processing all that snot. Plus, my back's been hurting for a week anyway. So, I have no idea if I have a virus.
