I would definitely have ended up just like you if I had tried a similar machine @Murphy2013, on ice. Just take it a little slower next time, better to ramp up slowly and be mindful of your knee the next day. It will tell you where the limit is.
I love this! So appropriate for many of us in this recovery! It might become my new advice mantra!Slow is the new fast.
I’m sorry you’ve had such a set back. To be honest, I don’t really think you should feel this bad 2 years out from TKR. You might consider yet another opinion.So I upped the swimming to unseemly lengths just to prove I could and kept going with walking same day until I have ended up laid up and sorely non mobile , icing and taking pain meds and feeling just as bad as I did after surgery,
I'm sorry you are struggling right now, but please know you are NOT alone! I just came back from a two-week trip (during which I walked miles and miles each day on uneven cobblestone streets)... and now I'm surprised by how uncomfortable my 14-m-o knee is. Hmmm. Some of us never learn!They should have added that you have a very unbalanced head and tend to need to get hit over the head before you learn anything!
