Wow,
@Needhope , you've been through the wringer, and many times. Others have already said what I would have said had I read everything as it was posted. But, having just finished your thread, I do have a few comments.
Pain meds-I have a major problem with reactions to pain meds so my OS has been jumping through hoops to figure out how to keep me out of pain without killing me with narcotic pain relief. But, whenever my pain has gotten unbearable, I get myself to the ER post-haste. The ER is equipped for that and will take care of you. They are also able to prescribe adequate pain relief upon discharge from the ER.
The anger I have for a doctor who decides you don't need, and can't have, adequate pain relief is beyond words. Believe me, if I had a doctor like that, after giving him a severe tongue lashing, I'd be haunting the ER, or my PCP's office, etc. I wouldn't allow anyone to treat me like my pain doesn't matter, or like it's my problem and I need to get over it, etc. Believe me when I tell you how much I hate pain meds, but if I need them I will take them. When I had my TKR I needed narcotic pain relief on a regular schedule for around 6 weeks if I recall correctly. Even with all the problems I had, and all the ER visits, and doctor visits, I had a lot of pain for a very long time, so needed meds for a very long time. But the very minute I no longer had pain I no longer took a single pain pill. I don't remember every detail, but did whine a lot in my thread as I recall.
As for your worry about negativity, crying, whining or whatever, my thread is filled to the brim with all of that. That's why this site is here and why it's such a blessing. We can come here with all our news, good and bad, and get support. Everyone here has been through this, which is very different from those around us who haven't been there, done that. Even the surgeons can't really understand as their job is to fix the knee, not get us through the recovery. Just as a male obstetrician can't really understand pregnancy and childbirth, but is able to deliver our babies, an OS doesn't really get the whole recovery process. He may have learned about it, but living it and seeing it are very different animals. So, come here to vent, cry, holler and yell on your bad days, and share your blessings on your good days. Over time your bad days will be fewer and your good days will take center stage, and others who need support will see that it truly does get better.
As for worrying and fretting about not doing enough, you need to give your knee what it needs in order to eventually give you back your life. I was not allowed to even use a cane until my six week check-up; until then I was to use my walker. I do vaguely recall trying to get my doctor to okay a cane earlier as I was able to walk around my house with it and it was easier to manage than a walker. I do know my current OS will likely keep me on a walker for six weeks as he wants to make sure I don't fall or overuse my knee before it's ready. I think you transitioned too early; six weeks may be too long for some, but your transitions are too fast IMHO. There's no shame in allowing your knee time to recover; if your house is messy, the police won't show up at your door and condemn your house.....
As for your daughters, you carried them around for 9 months 24/7 and have carried them ever since. If they complain about being too busy/stressed/new baby/school etc. they are using lame excuses to avoid helping, and should be ashamed of themselves. The daughter with the new baby is perfectly capable of putting said baby in a car seat and driving to help you at least one day a week. It's a win/win. You get to hold and love on the new baby while your daughter serves you as you have served her from day one. The daughter who is there in the same house will survive temporarily sacrificing her time and energy to cheerfully help you in your time of need, just as you helped her all her days. I have zero patience with self-centered children who are "too busy" for their mothers. This recovery will take at least three months just to begin feeling like a human again, and will take approx a full year before you are doing well. Three months of serving their mother doesn't begin to equal the years and years of daily sacrifice mothers give to their children without question. It's time for your daughters to grow up and think about you now.
I also think you may be a little slower in recovery due to inadequate pain relief, too much PT, exercise and housework. You have what, a month or so of leave left? Use that time to give your knee(s) as much TLC as possible. Get your daughters to help, and do no more than is absolutely necessary. Rest that knee; elevate and ice it as long as possible during the day, and non-stop at night.
I hope you can figure out your work situation; I have no advice nor comment there as I have no experience with that. But I hope you are able to get it all handled, and am glad you are able to take more time to recover. Good luck and keep us posted. Kim
