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

首先，有生物因素会放大到大脑的伤害性信号。

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

伤害性疼痛是指你实际的身体组织损，比如割伤、烧伤或骨折。

Most acute pain is nociceptive, which is to say nerves transmit information from the site of injury to the brain.

大多数急性疼痛是伤害性的，也就是说神经将信息从伤部位传递到大脑。

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的神经纤维比带有损伤性信号的纤维要更厚一些，摩擦伤口反而可不会那么疼。

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.

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

This signalling from damaged tissue along healthy nerves is known as nociceptive pain, and can occur in chronic form in such conditions as ulcers or osteoarthritis.

这种来自损组织沿着健康神经的信号被称伤害性疼痛，并且可以在溃疡或骨关节炎等疾病中以慢性形式发生。

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，医生会把你的断臂归类急性伤害性疼痛，因这种疼痛是骨组织损的结果，愈合后你可不会有任何疼痛。
