<s>[INST] Last night before bed I started getting waves of stomach pain. Everything 5 to 10 minutes. Feels like I am getting the wind knocked out of me. The pain is very strong and has caused me to vomit. I have not been able to eat, no appetite last night or this morning. 40 years old, female, weight 142 [/INST] Hi ! Good morning. I am Chat Doctor answering your query. If you had any food from outside, that could have brought in some intestinal infection, and accordingly you would have to go for an anti-emetic, and an antibiotic suitable for intestinal infections after consultation and a physical examination of your abdomen by your family physician. If no such history is there, I would advise you for an ultrasound abdomen to rule out stone disease of gall bladder or a calculus in the urinary tract, a urine test(routine, microscopic, and culture sensitivity) to rule out a UTI (urinary tract infection), and a routine blood test like CBC and blood sugar. Further management would depend on the findings of physical examination and related investigations. Till then, you could go for a proton pump inhibitor, a probiotic, an anti-emetic, and an anti-spasmodic for a symptomatic relief. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor. </s>
