Hello, 1. At present all I can say is that it might be a gastrointestinal symptom thus you should contact a general surgeon [to exclude appendicitis]. 2. symptoms of combined vomiting and diarrhea points towards food poisoning [gastro enteritis] thus you need to see your primary care doctor who might manage you symptomatically but may refer you to consult a Pathologist or an infectious disease specialist to know about the culprit behind the pathology, [i.e. was it viral, bacterial or parasitic infection] and then prescribe accordingly, till then: - wash hands properly [before eating, after using the washroom and after handling pets/waste]. - drink boiled water and properly cooked vegetables [avoid raw/ undercooked food and tap water] - wash all fruits and vegetables thoroughly before consumption. - Add probiotic food [curd, sourdough bread] which will help maintain proper digestive function] - take plenty of water, liquids, black tea, overripe bananas, coconut water. As loose motions decrease take soft diet, soft rice, bread, toast, cornflakes, dry fruits, salads. - Avoid aerated drinks, milk, chilies, deep fried foods. 3. The most common diagnoses of lower abdominal pain relate to uterine, gonadal, renal, and bladder complications, [less common causes like primary dermatologic and musculoskeletal problems as well as referred pain and neuropathies related to underlying vertebral and spinal cord complications can also occur], so examination is mandatory for further workup and management. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Munish Sood
