DD’s knee dislocated really badly. It popped back in but she is in pain and too scared to put any weight on it. Earliest physio is 3 weeks and I’m worried about it stiffening up. She’s stuck on crutches and limited as to where she can go. Also worried about her MH. She has autism, hyper mobility and ADHD. MH history and struggling with not being able to go anywhere. Is a 3 week wait the norm and ok?
