Yet another one

Yesterday was not a bad day. I had a relatively mild sinus headache. Today, I woke up feeling pretty good, but my around noon, I started getting a headache. I thought it was another sinus headache, but after taking 3 sinus tylenol, I took some Aleve around 2. There was still no improvement, it remained around a 3 or 4 on the annoyance scale. Finally, around 5, I had to break down and take an Imitrex that finally cleared up the migraine by around 9 or 10pm.
