Maybe I misunderstood, but are you saying you're doing the activities of week five on purpose, or without realizing you're overdoing? It's not a race to see how fast you can get through the list; rather a guideline as to what you should be doing so as to not overdo.
If your husband thinks you need to do more exercises, then tell him (ahem...calming pause and deep breath for a moment) you appreciate his concern, but you have to do what your knee tells you and what you think is best. I would personally be more succinct, but don't want to get into trouble here by saying what I'd actually say.......lol. If that doesn't work, then you might need to be more succinct. I have noticed many husbands who are caring for their wives after this surgery take that to mean they are also supposed to tell them what to do to recover faster or better, etc. Maybe it's a guy thing in that they like to fix everything; it's in their DNA. Who knows, but most are well-meaning and just need to understand the boundaries. I had my husband well-prepped this time around as to what I was going to do, or not do, and why, and where he was allowed to help and where he was not allowed. Last time he was inclined to follow the PT and kept nagging me to use the CPM more often and at higher numbers-I finally had to tell where he could put his (well-meant but wrong) advice.
My steri-strips took forever to fall off. I finally "helped" them meet their maker as I was sick of them. I don't know why they use them either, but many doctors do and they tell us to let them "fall off naturally". That may be fine for those whose strips fall off easily and quickly, but mine seemed gorilla-glued on and were't budging without some help.
