DD (6) has broken her arm and has an old-fasioned full length plaster of paris cast. This morning she says it feels tighter on her lower arm, and it does maybe appear a bit flattened but not cracked. Her arm is has now been in plaster nearly 3 weeks so shouldn't be swelling. It hasn't got wet, but I was wondering if she could have lain on it in the night, and as it was so hot her sweat (Ugh!) has moisened it and it's loosened. She's not a great historian so it's difficult to work out how tight it is - it's certainly not painful. Just wondering whether to go back to fracture clinic.
