My little girl fell and had a buckle fracture she got her cast off 3 or 4 weeks ago Now she has a rash on the same wrist she fractured Do you think this has anything to do w the fracture?

very unlikely that the rash is related. more likely it results from the irritaion of having a dirty sweaty stinky cast held to her sensitive skin for three weeks, or even a new surnburn on recently exposed skin. not related to the fracture, i assure you. hope that helps
