The past month my 10 year old has been complaining about headaches, nausea, stomach cramps, tiredeness, and lack of energy. Had him tested for thyroid, diabetes, had an abdominal ultrasound, tested his urine, and iron levels. All results came back normal. He says it s worse (nausea and tired) after drinking warm fluids or physical activity. I have had him at 2 Dr appointments but no answers. I need yo help my son but don t know what to do anymore.
