Infected dog bite? Need insight.?

A infection could become fatal when it is left untreated. I got a infection from constantly scratching my skin (because of dermatitis), and I ignored the infection on my arm, but it got very painful and disgusting after a few weeks. So, I advise to see the doctor. A infection may make you think it like a simple cold, but many unfortunate consequences may happen. Good luck! I hoped it helped.
