<s>[INST] Hi drMy name is nashat age 54. I have a heart condition. Since last 2 days iam having stomach pains and fever. I havent been able to go doctors but was concerned whether this may be related to my heart condition. Please advise me on this and the best medicine to take. [/INST] Hi Nash at ! Good evening. I am Chat Doctor answering your query. Even though heart problem could also mimic as a gases or acidity in the upper abdomen (epigastric region), we can not conclude on it without related investigations and a physical examination by your treating doctor. The fever with stomach pain points more to an infective origin like a food poisoning if you had any food from outside recently. I would also advise for an ultrasound of abdomen to rule any chances of a cholecystitis/cholelithiasis for the pain and fever. Till the reports of clinical examination and investigation reports are ready, you can take some proton pump inhibitor, a probiotic, and an antispasmodic Chat Doctor.  Further management would depend on the results of investigations and physical examination. 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. Wishing you an early recovery. Chat Doctor. </s>
