Hi! Since pain is different for everybody, "pain management" should be geared towards the individual. I would think consideration would be made as to what they NEED to do on a daily basis, what they WANT to do on a daily basis, and how the individual deals with pain.
I know my pain scale is less than most. What I would describe as a "3", the majority of people would rate a "5" or "6". If you are in pain, you need to scale your own pain and decide what is tolerable and what isn't acceptable. In my opinion, if you are able to walk without assistance and have minor "aches" as you walk, that , to me, would be "tolerable". However, if you are unable to function without sharp/stabbing pain, or pain that comes on so quickly that it makes you jump, but then goes away (a "quickie" as I call it), I don't think a pain medicine is going to help you when those things happen. It's the CHRONIC "pain"....I'm not referring to an "ache", as when your muscles are tired. We that are recovering still, will have aches, as we are working those muscles again. What needs to be determined is the difference between and "ache" and a "pain".
Describing your "pain" would be beneficial to those of us who will try to help you out. As Jo has told me, 6-8 weeks post-op isn't a whole lot of time, so WE have to be patient and know that our knee/leg isn't going to be pain/ache free for some time.
I do not take my pain medicine every day, and I know for those "sharp/stabbing" quickies, they won't help with that. If I know that I have to go out and grocery shop, I KNOW I won't make it through the store without PAIN that will stop me from wanting to walk. The CONSTANT pain and ache combined will set me on my butt faster than anything. Maybe it's because I'm overworking my leg? hhmmm...don't know.
I'm anxious for you to post and describe your "pain" and what triggers it. I'm guessing you are in "pain" at night because you are busy during the day. Your knee is answering back to your activity during the day. A heating pad helps me at night. PAIN doesn't wake me up at night, unless I turn over and bump my knee. Ok...that HURTS! Other than that, it's the deep ACHE that keeps me awake.
