Tall 12 year old girl

[Bordador]

Hello ... am looking for some advise and/or perspective.

My daughter turned 12 yesterday and is currently 1 m 66 cm (5 ft 4.5 inches). I have checked on the national statistics growth charts and she is above the 99th percentile. She is the tallest in her class and is beginning to feel very self-conscious as it's all anyone ever mentions when they see her. In theory she has another two or three years of growth ahead of her.
I've also noticed she has really fallen arches and her feet and ankles hurt her.

Would you ask the GP to measure her and keep an eye on progress? I know there is nothing you can do about tallness but I worry there may be some underlying pituitairy gland issue (my cousin had this when he was young and he is now a strapping 6 ft 8-er - but easier to carry that off on a boy).

In covid times I don't want to waste their time - but equally I can't let it go! For perspectibe, I am 5 ft 7 and her father 6 ft - so fairly standard.

Interesting thread, my ten year old is currently just over 5'5. Very tall and completely in proportion. I'm 5'7 and dad is 6'4, so it will be interesting to see where she levels off. My elder two are: 16 years old at 5'7 and 14 years old at 5'8. I'm destined to be dwarfed by them!
