I twisted my ankle really badly about 2 weeks ago (fell down 2 or 3 steps into my garage). I can fully weight bear, and there are times when it doesn't hurt or is a dull pain, and then there are times that it really does hurt quite a lot. Is it possible your Dd may not be saying she's in pain, but that its coming and going? (Oh , I also have no bruising and no swelling). I would definitely look into a stroller or a wheelchair, depending on her age. Walking on it a lot could aggravate the injury. Beyond that, take your drs advice on how to otherwise treat it.
