Theories:

a) I added a bit more air to my cushion.
b) It's -30 outside.
c) Someone upstairs is pleased with the prayers I've been giving them (none for pain relief) and decided to reward me with a little break. Why not with a total cure? Because I've learned that's not the way they work. They have their own reasons for allowing the pain to happen.
Or maybe these same parties realize that my files from the psychiatric institute are coming and that for me to handle both unmanagable physical and psychological pain would be too much for me and would lead to...regrettable results. (My friends upstairs have a lot invested in me.)
And my friends realize that I know that even a two day break is the most loving thing anyone can do for me, more valued than a million bucks at this point, and that I will be talking/thinking about this break for at least a month afterwards and thanking them profusely for it.
