I'm not sure what happened, either, but sometimes just a little thing upsets your knee for a while. If that happens, you have to spend some time pampering the sore knee again. Try to spend at least a couple of days resting, elevating and icing the poor thing. If you have pain at the back of your knee, try icing that. as well as the front. I know that, for about 9 months after each of my TKRs, my knee would occasionally decide to let me know I'd done something that upset it. It doesn't do it any more now.A couple days ago my bad (or worse of the two) knee started hurting and got very stiff. It hasn't been this bad in months. It continued to hurt really bad even after I elevated and iced. I don't recall doing anything unusual that might cause this--it really hurt. The one thing I can think of is that I was wearing jean capris that were rolled up to just below my knee. Maybe it was too tight. Much of the pain was from around my bakers cyst, maybe it squeezed and irritated it. I've worn these capris before without issue. It's feeling better now but still a little more stiff than usual. Any ideas or suggestions. I don't need this happening.
It's a good idea to ask your doctors what they think, especially as you're on anticoagulants.I'm also looking at taking some fairly long flights in May, not sure how to handle that. One doc suggested lovenox shots just before and after the flights. I'll see what the doc's this week think.
We do have an article that gives some general advice about foying:
Flying soon after surgery
I hope that helps.
