So glad to hear you are improving! 7 weeks was the magic number for me as well and from what I read before my surgery the 7-8 week mark was when most started seeing marked improvements in ROM.
Being pain free (well less pain anyway) for even a few hours is a nice relief and you will certainly know when you pushed things to far, your arm will remind you! I started walking my dogs with my hubby in the evening. We live on country roads so not much traffic and a few good hills to boot. It took me one walk to figure out I need to keep my surgery arm in my pocket when I am walking as I am an arm swinger when I walk- my arm was SCREAMING the next day. Now I am pulling it out for short periods and it seems to do better.
I live in NW Washington State and it seems our more rainy season is here(4 seasons-Wet, less rain, light rain, and get out the floaties) so I am going to give my elliptical a try, probably without the arms (or at least one) to start. Doc said if I get full ROM back before the end of ski season I can go. Since ski season is late to open (nothing yet) I am keeping out hope for a late season
Keep up the hard work with your PT. I found myself a few times this last week with the holiday letting myself not do my stretches and I am paying for it this week.
