Would they give me anything ? No, I should taper down. After only 2 weeks ? Crazy.
I, too, was told I needed to taper down & be off narcotics by two weeks post-op for my current right TKR! Unbelievable!
So, at 2 weeks & 6 days post op, I’m currently on Tramadol which somewhat manages by daytime pain but does very little for my nighttime pain. I had Norco four tablets (5/325 mg) left from those first two weeks and took two tablets each the past two nights. My pain was so much more bearable & my sleep felt somewhat restorative! I have no more Norco left for tonight & I can already tell that the Tramadol isn’t going to suffice for tonight....not going to be a fun night.

I’ll definitely be making a phone call in the morning!
I, too, have been through this previously (a year ago) with my left TKR but it doesn’t make the pain any easier. I totally understand your frustration & depression.
