I have an 8 yr. old granddaughter who constanly runs a low grade fever, complains of stomach aches, passes gas, and complains of headaches and leg pains. She has been examined and was told she is healthy but to drink more water. Is this what we call "growing pains"? Anyone out there know of kids who complain of these things? Regular blood tests were ok. Please help. Tylenol and motrin help for a short time. What else can I give her?
