<s>[INST] About three days ago I had the feeling of an upcoming flu (Had the chills, skin irritated, nausea). Then the day after I woke up for school and threw up. I threw up twice in the morning but didnt for the rest of the day. Then I went back to school came home and took a nap, I woke up and about 3 hours later I started to experience a very sharp pressure in my chest (In between my rip cage) I threw up more. The pain was unbearable and it would not go away. I broke out in a sweat. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Nausea, vomiting, central chest pain etc. are classical symptoms of HERD (gastroesophageal reflux disease). HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause symptoms of chest pain, nausea, vomiting etc. So follow these steps for better symptomatic relief in HERD. 1. Avoid stress and tension, be relaxed and calm. 2. Avoid hot and spicy food. 3. Avoid large meals, instead take frequent small meals. 4. Take pantoprazole and risperidone tablet on empty stomach twice. 5. Quit smoking and Alcohol if you have these habits. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
