Leg pain

Aub

Anyone else have a 5 year old or any age kid who has bad leg pain after playing on their feet all day? My child’s leg pain will only go away with Tylenol or Motrin. I have tried rubbing them, a warm bath, heating pad. Nothing works except medicine I’m afraid he is taking way to much. Anyone have any advice? He has been seen by a foot specialist as well and they say they see nothing wrong with him.
