I got my Cartilage pierced 3 days ago, twice. One of the piercings is really painful, it do not look like it is infected but it is incredibly painful. I want to take one of the piercings out. Will this increase my chance of infection?

I doubt it will raise the chances of infection. Just be sure to clean it when you take it out. Sometimes when when they hurt you should take it out for a few days and than stick it back in. my sister has told me to do so and it worked.
