That is just when I wake up, yes it is dark, I am a morning person. I get 6 to 7 hours a night of sleep, working on more. Funny you ask to give a 1 to 10 scale, my neighbor did the same. I would rate it a "6", my knee has improved considerably since September. I can now walk around stores etc without thinking "Oh boy I overdid it and am going to pay tonight". My knee is starting to have short periods of time when it does not hurt at all.
Next week I see the OS again, he is about 30 miles from here, so we go out to lunch after the appointment. It gives us something to look forward to.
The worst time of day is at around 3 am to 5 am when my knee just hurts, this seems to be a common pattern, and the cause of my lack of sleep. I am switching my Celebrex from AM to PM, hoping it will help.
At 8 months I figure I still have a ways to, probably another year before my knee fully heals.
