Step-by-step explanation:
It is important to watch for increased redness, swelling, and pain after a cut or abrasion has been cleaned and bandaged because these are signs of infection. Redness can indicate inflammation, swelling is a response to increased blood flow and fluid accumulation, and pain can be a result of tissue damage and irritation. If these symptoms worsen or persist, it may indicate that the wound is not healing properly or that an infection has developed, and medical attention should be sought.
