How long will weakness last after flu?

The time it takes to recover from the flu and its associated weakness can vary from person to person. In general, most individuals begin to feel better after 2-4 days. However, some people may experience symptoms for up to a week or longer, and weakness may persist for several weeks. Individuals with underlying health conditions or compromised immune systems may also take longer to fully recover. It is important to rest, stay hydrated, and consult with a healthcare provider if symptoms persist or worsen.
