As a mom of a 14 year old daughter... Not saying this is you- but kids complain about every bump and scrape especially when they are little. They get better as they get older, but my daughter still complains about being injured or not feeling well a lot and it's usually very minor things so I never take it very seriously. She plays sports and is sore a lot, sometimes she will say she stepped wrong and her ankle hurts, etc... I generally assume if she is seriously injured and needs medical attention that it will be obvious (crying, hard to walk, visible injury, wincing in pain). If it's something like a sore ankle that she can still walk on -- then id probably give her some advil and see if it gets better in a few days.

I'm glad I read this, because I will keep it in mind for the future. If your mom was an attentive loving parent then she probably just didn't realize how badly you were injured.
