Since your symptoms have lasted for 5 days, you should consult a doctor before taking medications like antibiotics or anti-diarrheals (such as loperamide), as they can sometimes worsen infections. Your immediate focus should be on hydration. Drink Oral Rehydration Salts (ORS), water, and clear broths to replace lost fluids. Stick to a bland diet (bananas, rice, toast) and avoid dairy, caffeine, and greasy foods. Please seek medical evaluation promptly, especially if you experience a high fever, severe pain, blood in your stool, or signs of dehydration like dark urine or dizziness.
