My child (6) has had his leg in plaster after a buckle fracture just after a month ago. It came off this morning (it was the third cast) and he is still screaming every time his leg is moved. Is it just normal stiffness / wasted muscles causing the pain or is it still not healed? I don't know what the pain is normally like when a cast comes off. They didn't X-ray him after it was removed.
