What symptom might suggest a muscle contusion?

The presence of pain and bruising is the hallmark indicator of a muscle contusion. A muscle contusion, often referred to as a muscle bruise, typically occurs as a result of a direct blow or impact to a muscle. This impact causes damage to the small blood vessels within the muscle tissue, leading to bruising and swelling in the area. The bruising is often visible on the skin and is accompanied by local pain, tenderness, and possible swelling.

In contrast, options like dry and leathery skin do not pertain to muscle injuries but rather could indicate dehydration or skin issues. Chest pain frequently points to cardiac problems or respiratory issues and is not linked to muscle contusions. Numbness may suggest nerve damage or circulatory problems rather than a muscle bruise. Thus, the clear association of pain and bruising with muscle contusions makes it the correct answer.
