‘剧痛’ literally combines 剧 (jù), meaning 'intense' or 'severe', and 痛 (tòng), meaning 'pain'. Together, they form a noun meaning 'sharp pain' or 'acute pain' — a sudden, intense, often unbearable physical sensation. Unlike general terms like 疼 (téng) or 疼痛 (téngtòng), 剧痛 emphasizes severity and urgency, commonly used in medical contexts or when describing sudden injuries, illnesses, or emergencies.

This word is formal and clinical but also appears in everyday speech when someone wants to stress the extremity of pain — for example, after an accident or during a severe headache or stomachache. It rarely describes emotional pain; for that, words like 哀痛 (āitòng) or 悲痛 (bēitòng) are preferred. Native speakers often pair it with verbs like 感到 (gǎndào, 'to feel'), 遭受 (zāoshòu, 'to suffer'), or 出现 (chūxiàn, 'to occur') to describe onset or experience.
