@dkapustin -- I am sorry about the amount of pain you are in! I don't have any experience regarding pain with Total Knee Replacement; however, I do know pain! So, if it were me, I would make an appointment with the surgeon. We all feel we are being "silly" for going "ahead of schedule", BUT we are all different, not to mention that there could be other reasons for your pain. Let the surgeon tell you if everything is OK. And if it is, maybe he can give you advice on how to handle the pain, or medication suitable for your level of pain. Stay well!

Time, I think, will be eventually easing the pain. Hope that you can get help from your OS for now. I did not have a turning point either, it just got less as time went on. Sure, I could have taken OTC medicines like Aleve - the only thing that seems to work for me - , but I prefer not to stress my system with too much stuff. Also, as far as I was concerned, what’s the ultimate point of having had the TKR if I still needed daily pain medication? If I wanted to dose myself up to the limit, I could perhaps have waited another year or so. Summary: it will certainly get less painful, and I hope this happens soon for you. It did not, however, totally eliminate temporary pain at a medium to low level, at certain times (like weather changes, or intense activities like yard work), but I did not expect it to. Hoping, yes. But alas, no.
