Ow.

My knees are hurting today. They started hurting last night. Come to think of it, my head hurts a bit too... and my fingers, and my shoulders and neck. And my arms. But my knees are definitely the worst.

For the record, here's the current stats at environment Canada:

Temperature 21°C
Pressure/ Tendency 101.9 kPa↑
Visibility 24 km
Humidity 68 %

(My allergist suggested I keep a diary indicating both when I hurt, and what the weather's doing.)
