<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 41 hear old female. I have been experiencing mild stomach pain accompanied by bloating and gas, on and off for the past few months. It mostly occurs after meals. Tonight I woke up sweating and have stomach pain and diarrhea. I took my temp and it is below 96. I have had 2 or 3 episodes where I became nauseas and vomited within hours of eating a heavy meal. I happened to have a heavy meal earlier tonight. I am starting to feel better now. I have had an abdominal ultrasound and upper endoscopy within the last few months and botChatDoctore back fine. Blood tests came back normal as well. But I continue to have the same stomach issues. Any ideas on what could be the problem?  <response>: Hello your symptoms suggests of gastric upset.I would advise a patient like you norfloxacin 400 mg plus tinidazole 400 mg 12 hourly, omeprazole 20 mg plus risperidone 30 mg half an hour before meals, also you can take any anti-spasmodic like spasming every 8 hourly.take plenty of fluids. Avoid spicy and fatty foods. Follow this prescription for 5 days and if then also you find no relief visit your general physician. Hope it helps
