my kids all have growing pains- they are horrible - my DH and I both had them as well
they are heridetary as well
my poor DD has severs disease as well- look it up it as bad a broken bones and affects the heels and feet etc
my DD gets them really bad in her feet and the pain radiates up her legs and knees as well
Ice, nurofen/ votaren gel works. Treat them like you treat a sprain. My DD wears foot braces when she gets them for support and extra supportive shoes.
Massage works well .
