20 week update:
Improvements: Can turn fairly easily at night if I support lower leg. Down to 1 pillow. Only take OTC meds occasionally when necessary. Almost no pain on resting. Can carry a bit of weight now. Massage whilst having toes above nose really helps.
Setbacks: Not driving at all now, takes about 2 weeks of resting afterwards if I do and this just isn't practical long term. Pain and swelling after any activity, even walking round the house and the swelling has reduced my flexion back to 90 making walking normally almost impossible. The awkward gait also makes me unsteady and more prone to tumble. Was almost able to climb stairs a few weeks ago, hanging onto the rail, but no longer possible as I can't lift leg high enough unless I swing it out to the side first. I think all the previous resting has caused some Quads muscle loss so am exercising to improve this. My pattern seems to be increased pain and swelling after any mild activity, which seems to take at least 10 days to get back to where I was, but then a very slow, creeping improvement. Truly 2 steps forward and 1 back!
