Paraphrase: For instance, individuals who have previously endured pain have reported a greater sensitivity to pain compared to those who have never experienced pain, even if they are not currently in pain. Moreover, past experiences of severe pain can lead to heightened pain reactivity. Past pain experiences also influence the effectiveness of placebo pain relief. The present state of pain is another factor that influences pain perception. When individuals reflect on past pain experiences, they gauge their severity based on their current pain experience. Furthermore, current pain can shape the perception of past pain by assimilating it.
