Hello and welcome I share your concern looking at your description it might be related to stomach hyperacidity or gastritis or food poisoning I would advise you to take antiacidity medicines like pantoprazole or ranitidine group of drugs with antacids and antiemetic like domperidone or ondansatron for vomiting if it doesn t subside in a day or two than you need to see a gastroenterologist for an endoscopy if need be. You should avoid fatty fried spicy and junk food Have lots of fresh fruits, fruit juices and vegetables However I will be requiring more information for better assessment of the condition like Since how long you have this problem? your built, height and weight? if you oredered for blood tests or other investigation, please upload me the reports? your relevant medical history like diabetes, high blood pressure or any other disease waiting for your reply Best wishes
