Hi! Good evening. I am Dr Shareef answering your query. Most likely you have got a food poisoning, specially if you eat from outside. If I were your doctor, I would go for a routine stool test for ova and cyst and a culture sensitivity test, and treat this if positive. I would also advise you to get your blood pressure checked and then get yourself assessed by a medical specialist. Further management would depend on the reports of investigations. 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 health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
