<s>[INST] Hi, Today i noticed my 5 yr old daughter s vein on her right leg looked so visible. She has been complianing now and then that her legs hurts. We have talked to her pediatrician about that before and she said its just a growing pain. I am kinda worried if that has something to do with her legs hurting? She still wakes up inthe middle of the night complaining about her legs hurt. [/INST] Veins may become prominent during growth, however it doesn't really have to do much with pain. Get her vitamin D levels checked and give ample vitamin b + calcium+ vit D supplementation after the tests. This should bring the pain downI hope this answer helped </s>
