Which of the following is NOT a common sign of a nail infection?

White spots on the nail are generally not considered a common sign of a nail infection. Instead, they may indicate other issues, such as trauma, minor injuries, or an underlying health condition. Infections typically manifest through symptoms that are more directly related to inflammation and irritation, which include redness around the nail, swelling near the cuticle, and persistent pain in the nail bed. These signs indicate that the body is responding to potential pathogens or irritants affecting the nail and surrounding area, which is characteristic of an infection. Thus, recognizing white spots as unrelated to infections helps in identifying actual infection symptoms effectively.
