It is not uncommon to have multiple piercings performed on the same day. We recommend not getting more than four piercings in one session, especially if you’re getting them on the same ear. Getting multiple piercings can also cause increased swelling during healing and can prolong healing time.nnBe mindful of getting cartilage piercings on both ears at the same time as it can be difficult to sleep. Handy tip: Sleeping on your back is ideal, but you can also use a U-shaped travel neck pillow so that you can sleep on your side if you’re strictly a side-sleeper!
