Which of the following is a common symptom of cellulitis?

Redness and swelling in the affected area is indeed a common symptom of cellulitis. This bacterial skin infection manifests with inflammation, which typically causes the affected area to appear red, warm, and swollen due to the body's immune response to the infection. As the condition progresses, the skin may become tender and may also feel tight or stretched. Recognizing these signs is crucial because it helps in timely diagnosis and treatment, preventing further complications.

In contrast, dry skin and a scaly appearance, dark colored patches, and excessive perspiration are not characteristic symptoms of cellulitis. These could be indicative of other skin conditions, but they do not reflect the typical signs associated with this bacterial infection. Understanding the prominent signs of cellulitis helps in differentiating it from other dermatological issues, thereby aiding in effective management of the condition.
