I just received my phonak Cros hearing aid and I had many piercings. Between both ears I had my tragus, industrial, rook, orbital, and the forward helix. I took them out as they made my hearing aid a bit uncomfortable (not all of them, but I still decided to take them out, the orbital and rook were fine). Although, this was an easy decision as I'm 22 and I got to fully enjoy all my piercings. Like everyone said, I'd wear them when you go to the piercer, but keep in mind as it's healing it can't be in contact with anything or it runs a risk of infection or taking a very long time to heal.
