Hi Sue!
I thought I'd be smart and say something in French, but after 5 years of French, the only thing I can really do is say swears, which aren't permitted here in any language.

Anyway, I just finished reading your posts and your recovery sounds familiar. This is a very long process, and for some of us (me-in particular) takes way longer with multiple detours and lots of worrying and tears.
At some point (for me, MANY points) in recovery, most of us feel like we are not only going forewards, but going backwards. That is normal too.
I am sorry you are still having discomfort. The weather just aggravates the annoyance. You could be dealing with an IT band issue. I had that after my TKR (I've had a revision-long story). I used heat and gentle massage (when I massage vigorously, it feels worse).
In any event, you are moving along at an appropriate pace, for us slower types. You have plenty of company there!
Your Surgeon sounds wonderful BTW. You are lucky!
Best,
Sandy
