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

首先，有生物因素会放大到大害性信号。

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.

如果你从秋千上掉下来，医生会把你断臂归类为急性害性疼痛，因为这种疼痛骨组织受结果，愈合后你可能不会有任何疼痛。

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.

而且由于有触觉信息神经纤维比有性信号纤维要更厚一些，摩擦口反而可能暂时不会那么疼。

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

害性疼痛指你实际身体组织受，比如割、烧或骨折。

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.

心因性疼痛指恐惧、抑郁、压力或焦虑使常规害性或神经性疼痛感觉比正常情况下更糟或持续时间更长。
