My son is 11. He has had terrible burning, throbbing pains in his upper abdomen along with a tightening sensation in his abdomen, urinating frequently, leg muscle aches, nausea, dizziness, insomnia & gets motion sick when on a boat or in a car. These seem more like attacks, coming on all of a sudden, lasting hours-days. He has been to his Dr. several times, emergency room & had numerous tests & is now seeing a pediatric gastroenterologist. He was prescribed prilosec 2x daily. The medication is not helping, he has been on it 3 weeks. He had another attack this past weekend, lasting the entire weekend. Today the specialist sent him for another abdominal x-ray.
