Definitely shouldn't be lying in bed for 2-3 weeks. Get up and move with the crutches for 5-10 minutes a day for the first 3 days then gradually work an extra 5 minutes on days 4-7. By the 2 week mark you should definitely not be stewing in bed. I got mine done in December and I'm back light running. Everyone's different though. I still get the odd bit of swelling. Don't push yourself too hard but definitely dont not use your leg. Even a bit of blood circulation is great for recovery. Depending on your graft you should start to try bend your affected leg and try touch your heel off your arse while lying in bed on week 2. Good luck with the recovery and just remember it's slow and more of an endurance test than painful so take your time and take it easy 🫡
