What are common flu symptoms?

Common flu symptoms typically begin suddenly and can vary in severity, but the most frequent signs to watch for include: - **Fever**: Often high and sudden, though not everyone with the flu will have a fever. - **Chills and sweating**: Feeling cold one moment and sweaty the next. - **Muscle aches and body pain**: Generalized soreness, often quite intense. - **Fatigue and weakness**: Feeling very tired and drained, which can last for several days. - **Headache**: Moderate to severe headaches are common. - **Cough**: Usually dry and persistent. - **Sore throat**: Irritation and pain in the throat. - **Nasal congestion or runny nose**: Stuffiness or clear discharge. - **Chest discomfort**: Sometimes a feeling of tightness or mild chest pain. Recognizing these symptoms early can help differentiate the flu from the common cold, which tends to have milder symptoms and less intense fatigue or fever. If symptoms worsen, especially with difficulty breathing, chest pain, or persistent high fever, it’s important to seek medical attention promptly.
