Do people ever heal from a staph infection, my sister says they dont. i know someone who has one and was wondering if they can get rid of it. so do th?

Of course they do!: I've treated hundreds of cases of Staph infection and absolutely most of them get better and completely resolve. There is something called a 'carrier state' which is where your sister might be getting confused. If you know someone with a Staph infection- I would direct them to an Infectious Diseases doctor who would be best able to help them (and any contacts who are concerned). Hope this helps.
