Final answer:
Increased redness, swelling, and pain after a cut or abrasion has been cleaned and bandaged can be signs of infection, and it is important to monitor these symptoms and seek medical attention if they worsen or persist.
Step-by-step explanation:
When a cut or abrasion becomes increasingly painful, swollen, and shows signs of increased redness, it could be a sign of infection. Infections can occur when bacteria enter the wound, and the body's immune system responds by causing inflammation. The increased redness, swelling, and pain are signs that the body is trying to fight off the infection. It's important to monitor these symptoms and seek medical attention if they worsen or persist.
