I would advice you to have antipyretics and antacids. These following steps could be of help: - Avoid cold food and water, preferably have hot food and water - Don't skip meals have a liquid diet containing soups and progressively increase to solid diet as per how you can tolerate. - Have food rich in vitamin C such as oranges to help build immunity. - Drink plenty of fluids, drink 3 liters of water per day - Maintain good personal hygiene(Wash you hands regularly) - Rest plenty, body heals while at rest If the condition persists or worsens visit nearest ER at earliest
