It sounds uncomfortable to have a fever, cough, and cold starting suddenly. For now, you can rest, stay well-hydrated with warm fluids like herbal teas or soups, and use over-the-counter fever reducers such as paracetamol if needed.

Since your symptoms began this morning and include fever and cough, it’s important to monitor for worsening signs like difficulty breathing, persistent high fever, or chest pain. Avoid self-medicating with prescription medicines like Relent Plus Syrup without a doctor’s advice, as it contains specific antihistamines and mucolytics that should be used under medical supervision.

If symptoms persist beyond a few days, worsen, or you have underlying health conditions, please consult a general physician or a pulmonologist for proper evaluation and treatment. If you experience severe symptoms, seek emergency care immediately.To narrow down potential causes, we will need some more information.Please tell me your age and gender.
