Should I try piercing again?

My ears were pierced when I was a child from a gun. I know those are not good for you and to go to a quality piercing shop where they use needles if I get pierced in the future. When my ears were pierced previously, I constantly had red irritated ears and we're very prone to getting infections. My ears never healed in the sense that after 2 decades if I had my earrings out for more then a couple hours they would begin to close. I did have my cartilage done by a piercing shop and had little ko trouble with that one. Ultimately, I decided to remove them all during a period where they were not infected or irritated and they have closed almost completely. I have been considering new piercings but am worried I will experience the same problem. Could it have been because my ears weren't pierced properly?
