hi, I am a 16 year old, I have constantly felt nausea , heartburn and indigestion whenever I ate. Sometimes i cannot even sleep at night. Along with that I have had some upper abdominal pain (stomach area) as well as pain in the right side of my back towards the upper part of my abdomen. I have been to a nephrologist and have had full tests for my kidney, liver, gall bladder , as well as urine and blood tests, showing negative results. I really haven t been feeling well at all and I have started to feel dizzy these days. Any suggestions?
