That's the worst of it. But after I'm up and moving around for a few minutes, the pain subsides to a dull throb, which is a nuisance but bearable. And the worst moments have dropped down a notch from "excruciating" to "miserable". So there's that.
I let myself go without pain pills for about a day and a half after the prescription ran out, just to purge my system and keep myself from becoming over-dependent on the pills. Refilled the scrip tonight at Walgreens and am now a comparatively happy camper. I think in another week's time I'll be in fairly good shape and won't need to bother with the pills anymore.
