If a finger looks infected four days after an injury, what should you do?

If a finger appears infected four days after an injury, it is crucial to see a healthcare provider immediately. An infection, especially one that does not show signs of improvement within a few days, can indicate a worsening condition that may require professional treatment. A healthcare provider will be able to assess the extent of the infection, potentially prescribe antibiotics if necessary, and provide appropriate wound care to prevent further complications.

While other options may seem applicable in different contexts, they do not address the urgency posed by a potential infection. Waiting longer could allow the infection to spread or worsen, applying ointment without professional guidance may not adequately address the issue, and simply keeping the finger clean and covered does not resolve the underlying infection. Seeking professional care is the most appropriate action in this situation to ensure proper treatment and recovery.
