You say your daughter is bendy and does gymnastics etc,this could be hypermobility due to her bending for sport etc but all children are bendy but some remain and get pain. I am an adult in my 40s and yet to be formally diagnosed but have bendy joints and have suffered years of pain. I have had many orthopaedic doctors treat me over the years but none pick it up until recently i mentioned my son and now they say i probably have. I would suggest getting your daughter checked. Does she have flat feet? My son does and gets severe pain if not using his insoles. Hope this is some help
