Since your fever of 102F and diarrhoea persist despite 3.5 days of Nizonide, and you are on IV fluids, immediate medical re-evaluation is crucial. I recommend: 1. Stool & Blood Tests: A stool culture and CBC to identify the exact cause (likely bacterial). 2. IV Antipyretics: IV Paracetamol to safely manage your high fever while you are nil-by-mouth. 3. Alternative Antibiotics: Your doctor may replace Nizonide with targeted IV antibiotics (like Ceftriaxone), as Nizonide may not be effective against this infection. 4. Electrolyte Monitoring: Ensure your electrolytes are monitored. Please consult your attending hospital physician immediately to update your treatment plan.
