<s>[INST] Hi I am 30 years old and get severe epigastric pains associated with nausea and sometimes vomiting occurring about 4 days before my period and lasting about one week after. This has been happening for the last 2 years. I have been taking omeprazole and various antacid syrups with no improvement. Any thoughts on what this is? [/INST] HI. This means your symptoms are related to the premenstrual syn Chat Doctor.  You may have an additional treatment like : Go for a proper diet and medicines-you will be fine:::*Soft bland diet without oil and spices.*Sanitizing 150 twice daily.*Risperidone thrice daily.*Antacid gel 3 tea-spoon-full every 3 hours, the first dose on getting up. If you do not get relief within 1 week - go for upper GI Endoscopy and a consultation with Gastroenterologist. </s>
