I am not Jo or Jamie, but I stopped all the narcotics about 4 weeks ago, and have been having trouble figuring out what will stop the annoying ache/throb in the knee, I had TKR Aug 4, you had 2, I had 1, but same pain....
I am now per Jo and Jamie taking every 6 hours 2 tylenol extra strength and 2 advil. Seems so far to be doing the trick. The new PT person I have now also massaged the heck out of my knee, just around the knee, knee cap, right below it, and around the sides, said that I had a lot of tissue that was stiff, need massaging, kneeding, to break it up, and that was causing part of my pain....now, yes, its better today, I am massaging it too, wasn't doing that area around the knee, and it seems to be a bit better.... hope you figure out with the meds, not fun, this TKR, but we are headed in the right direction.
