Hi Pinot, we are at roughly the same place- I am two months out today. My knee blew up on me also, complete with a stupid bulge on the side. I was apparently "doing too much". So these past few days I have totally slacked, and my do-nothing strategy seems to be paying off. I've tried compression and continuous ice, but the only thing that really seems to help is staying off it, plus elevation. Unfortunately today I must get out and about. Though sometimes I feel desperate to be back on my bike and/or back to some semblance of normal, I'm just not ready for that level of activity.
I measured my swelling for the first time, and it isn't as bad as I imagined- the TKR knee is only 1/2" bigger around than my "good" knee, but keep in mind my good knee isn't that good. I hope you get good news from your PA.
