Hello, Thanks for posting on HCM, In order to be able to assist you specifically, I would have loved to know exactly at what quadrant or level of the abdomen she is feeling the pain. Vomiting is the body’s way of ridding itself of harmful substances from the stomach, or it may be a reaction to something that has irritated the gut. If she has an associated vomiting of bile, then it could be as a result of one of several causes which could be: - Acute gastritis or peptic ulcer - GERD - Gastroenteritis: infection of the gut caused by bacteria or virus or fungus or amoeba - Bowel obstruction - Hiatus hernia etc. Now, a doctor should be able to examine her, run some tests and determine the cause of her abdominal pain which will enable proper medications to be provided. I suggest that you take her back to the ER for proper evaluation. Hope this helps
