DD (age 17) sprained her ankle. She could barely walk at first, but it's getting better each day - currently (day 3) no longer painful but she's still limping. She is insistent that it 'might be ok' to do a 1500m race at school on day 6 after the injury. She says she has warned her teacher she might need to be replaced, but 'will see how it feels'. I have shown her the NHS guidance which says to avoid strenuous exercise for up to 8 weeks. I want her to make the right decision herself, but if she doesn't take her head out of the sand, AIBU to consider contacting the school to make it absolutely clear I don't want her to run? I know they like to be independent at this age but I'm not convinced she has told school the exact nature of the injury, so don't think I can rely on the teacher to stop her running without my intervention.
