I had total knee replacement 4 weeks ago. I'm still in rehab for another week and doing very well. The last week or so I haven't been wearing the compression stocking. I was on my feet today for a couple hours and had both swollen ankle and knee, which seems common right now. After getting home I immediately elevated my leg and put ice on knee and then on ankle. That was a few hours ago. My ankle is still slightly swollen and slightly uncomfortable. Not sure why....difficult to sleep. I don't know what a blood clot would look like and would it start in my ankle? Just nervous...
