Hi Diane, my ROM was *terrible* at 13 days when I went to my one-and-only PT appointment (for staple removal). My extension wasn't great and my flexion was 45°. PT-dude-from-hell threatened me with a MUA

. I also took two percocets before that appointment. Thank God! I probably would have hit him if I hadn't.
When I went to my OS follow-up at around six weeks, he said my extension was great and to stretch some more to improve my flexion, but overall was very happy with my progress. SO!!!! Just get the swelling down and stretch as you can (heel slides), and you'll be fine. Don't stress over ROM at two weeks.
I find it interesting that OSs have such different ideas on recovery. My OS does NOT like PT at all. Pre surgery he said, "if you go, do NOT let them touch you!!!" and in my follow-up appointment he asked if was going and when I said no, he replied, "GOOD!"
Another tip for the ice machine: I will lay the pad flat and let it run while I use the restroom, just to let the water circulate. You can also disconnect the coupler and use a skewer to press on the valve to empty the sleeve, assuring cold water will completely fill it.
