Severe pain is characterized by its high level of intensity. It is often described as excruciating, unbearable, or agonizing. The pain can be so intense that it dominates a person's attention, making it difficult for them to focus on anything else. In contrast, moderate pain is less intense and may be described as uncomfortable, achy, or distressing, but it does not reach the same level of intensity as severe pain.
