No worries you are way early yet. Normal feeling for a while yet. If all is well a good pt will get you through. If you can when they say it’s okay deep water aerobics is good. If you are o and 122 for extension and flexion at 7 weeks that is awesome. It took me little over 3 months before I could sleep through the night with no pain. My therapist addressed all my issues including gait as that was issue for me as well. I also had him teach me how to get up if I fall or am kneeling. Sounds like you are doing great!
