I had leg pains growing up and they were often worse at night. My parents used to make me a warm foot bath, which helped. Adding Epsom salts is a great idea. When I got older and didn't want to get out of bed, I'd put a long, warm sock on the leg or legs that hurt. I don't know if this is out of date or not, but my pediatrician recommended that I eat more bananas since the potassium would help.
