Update: I had my 6-month check up and surgeon said X-rays looked perfect. Metal fused well to bone and spacing is as it should be. Now at 7 months I may have turned a corner with skiing . Pain has dropped quite a bit, swelling continues to decline very slowly. Last couple days on slopes have felt better. Continuing to work ankle exercises of movement and stretching along with balance exercises. Remaining cautious, not skiing downhill too often, and listening to pain. XC skiing is good except for the when I need to push heels out (snowplow) to slow speed on hill where I get a bit of pain. Still feeling weird nerve issues here and there. I was diagnosed with tarsal tunnel syndrome a few years prior to TAR. It had gotten better over the years but now that feeling of "lumps" on bottom of foot is pretty notable, but it's minor in the grand scheme.
So, I'm encouraged and hoping for continued improvement. It's a long haul but is slowly improving with time.
