Could frequent stomach pain and vomiting in the morning be a sign of appendicitis or issues with the gallbladder?
Patient: My son is 16, he has had on and off stomach pain for the last year. He also throws up in the morning and once he does he feels better. Today he says he has middle to right side pain and is very tired. Our general practitioner has proscribed him antibiotics. And his pediatrician in the past just told us to take antacids. Could this be his appendix or gallbladder? Look forward to hearing back from you. Thank you, JT Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  As per my clinical experience, your son can be having different possible conditions which can present as stomach pain and vomiting as - gastritis - indigestion - appendix inflammation - mesenteric  Lymphadenitis - recurrent intestine infection - gall bladder, biliary drainage system derangement  - others  To find out the underlying cause, I recommend basic lab tests with CT scan of abdomen & pelvis during the period of acute pain episode.
