My 19 year old son has Spherocytosis and has gall stones because of it. He has been suffering with heartburn, stomach/intestinal pain, alternating constipation and diarrhea and is vomiting daily. It would be hard to believe he has an ulcer since he doesn t drink, smoke or take nsaids or ibuprofen either. But I m not a doctor. His doctor for his blood condition has finally sent him to his primary care physician that he will see Monday. Any ideas?
