What are common symptoms of a human or animal bite?

Pain and swelling are common indicators of a human or animal bite, as these injuries often lead to inflammation in the affected area. When a bite occurs, the body's natural response is to increase blood flow to the area to facilitate healing and fight potential infection, which causes the classic symptoms of redness, warmth, and swelling. Pain is usually experienced because the tissues around the bite are damaged, and the area can be sensitive due to inflammation and possible nerve involvement. These symptoms help to signal the individual to seek medical attention, as bites can lead to infections that may require treatment.

Other symptoms, such as redness and itching, blackening of the skin, or fever and chills, may also be present in certain cases or due to complications; however, pain and swelling are the direct and immediate responses typically observed after a bite incident.
