<s>[INST] Hi. I am having severe stomach ache since last night. Yesterday I had milk in morning and a south indian dish dosa in dinner. Even before having dinner I was start getting the ache. However, after having dinner, the pain became worsen. I had taken medicine ranitidine in the morning. But still no rescue. Please suggest [/INST] Hi, Welcome to Healthcare magic. if it is a gastritis or a peptic ulcer pain which are very common causes of abdominal pain, you should have got at least some relief with ranitidine and food intake. Since there is no relief, i would advice you to visit your doctor's office to rule out conditions like pancreatitis, cholecystitis, etc. A clinical exam and certain blood tests, ultrasound scan may be needed  to come to a conclusion. I wish you a speedy recovery. </s>
