7When to Visit a Doctor
In most cases, keeping the body hydrated and resting well is enough to recover from a hangover and fever. But if the symptoms persist for a few days, it is important to seek help from your healthcare provider. The same holds true when you notice series problems, such as blackouts, tremors, or vomiting blood. A low-grade fever between 37°C and 38°C is no cause for concern. But when the body’s temperature exceeds 39°C, seek medical support immediately. [7]
