KOed by sinus headache

I wasn't feeling too well yesterday.  With all the symptoms like sore throat, I pretty much knew that it was flu.  So I kept drinking water and rest on bed.  I felt so much better this morning, so I thought the fight was over.

I was wrong.

At around noon, I started to feel sinus headache.  It got more and more painful until a point that I couldn't bare it anymore.  So I had to leave office at around 5:30 pm.  Once I got home I head straight to bed, and slept all the way til 9 pm. 

I am feeling better now, but the sinus headache hasn't go away yet.  So I am afraid that there will be another battle waiting for me tomorrow.  Sigh.
