6 week ear piercing swollen not red not itchy no pain except from the swellness why is it swollen?

A lot of piercings tend to swell up, it just depends on how the persons body reacts to the piercing really. To make the swelling go down take some ibuprofen and that'll help you out. I had to do that with my right nostril piercing. I was stoked when I saw the results.
