Our little one had a toddler fracture which she still walked on and played without issue, she even kicked the Doctors with it to which they said "yes definitely not broken" had the X-Ray where they swiftly changed their mind and told us to watch it as it needed a cast to be put on. They wanted us to keep her off that leg while in the cast too... yeah that didn't happen either. No swelling, no brusing, nothing to show that it wasn't right apart from her complaining at random times. It can't hurt to get it checked.
