A little negligence while chopping vegetables or working with sharp objects can land you in deep trouble. A little cut on your finger may seem harmless and not-so-painful initially. However, if you fail to attend to it, it may lead to infection, which can be pretty nasty. The main reason why minor finger cut turns into more painful infection is because people tend to ignore it, thinking, it'll heal all by itself. The truth is that, just like any other injury on your body, this minor injury needs as much attention.
