Should I get my ears re-pierced?

Okay here's the story, I had my left earlobe pierced a while back, and like last year. So I had it pierced twice, and I had my right ear pierced only once. Both holes has closed up but now I want to get them pierced again but the only thing that is stopping me is these small little bumps/ball thingies in my lobe. I just don't want them to like keyloid and get all ugly basically. I just want to know do you think that it would be safe to get them repierced ?
