First, there are biological factors that amplify nociceptive signals to the brain.

首先，有生物素会放大到大脑伤害性信号。

If you went flying off the swings, a doctor would classify your broken arm as acute nociceptive pain because the pain was a result of damaged bone tissue and you likely won't have any pain after it heals.

如你从秋千上掉下来，医生会把你断臂归类为急性伤害性，为这种骨组织受损，愈合后你可能不会有任何。

And since the fibers carrying tactile information are much thicker than those carrying nociceptive signals, rubbing an injury can produce temporary relief from the pain.

而且由于带有触觉信息神经纤维比带有损伤性信号纤维要更厚一些，摩擦伤口反而可能暂时不会那么。

Nociceptive pain is when your actual body tissues are damaged, like with a cut, burn or broken bone.

伤害性指你实际身体组织受损，比如割伤、烧伤或骨折。

Psychogenic pain is when fear, depression, stress or anxiety make a regular nociceptive or neuropathic pain feel way worse or last way longer than it normally should.

心性指恐惧、抑郁、压力或焦虑使常规伤害性或神经性感觉比正常情况下更糟或持续时间更长。
