<s>[INST] I am a 21 year old male and wondering what can be wrong with me. For the past two weeks as soon as I eat anything I feel really sick. Sometimes I start vomiting quite badly, I have also had a pain at the top of my rib cage for about a week. It starts off like a hunger pain and then gradually gets worse. I have been bend double with pain today.I am normally fit and healthy am 6ft 2" tall and weigh 15stone. Any help appreciated. Thanks Sean [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Since your pain is associated with eating, and you are also having vomiting, so possibility of HERD (gastroesophageal reflux disease) related symptoms is more. 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 and vomiting. So follow these steps for better symptomatic relief in HERD. 1. Avoid hot and spicy food. Avoid junk food. 2. Avoid large meals, instead take frequent small meals. 3. Take pantoprazole and risperidone combination on empty stomach. 4. Quit smoking and Alcohol if you have these habits. 5. Avoid stress and tension, be relaxed and calm. 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>
