很少有一些小伤能够像被纸划伤那样让人疼痛和害怕。光是想一想可能就让你不寒而栗了。然而,这种划伤通常伤口很小、很难被察觉到并且不怎么会流血。那为什么被纸划伤会这么疼呢?被纸划伤跟被剃须刀片划伤很像,但是有一点不同。剃须刀片造成的伤口较为平整,几乎不会留下任何会导致伤口感染的异物。虽然刚被剃须刀片划伤的时候很疼,但是过几分钟疼痛感就会慢慢消退。 Few minor injuries can be as painful and scary as paper scratches. Just think about it may make you shudder. However, such scratches usually have small wounds that are difficult to detect and less likely to bleed. So why the paper scratches will be so painful? Scratched paper was scratched with a razor blade, but a little different. Razor blades cause a smoother wound, leaving almost no foreign body that can cause wound infections. Although it was painful when it was scratched by the razor blade, the pain gradually subsided after a few minutes.
