Why do my ears keep healing up?

When I was 16, I got my ears pierced (at Claire’s, which I since learned wasn’t the best idea). I wore gold studs for a year and then took them out. I only wear earrings on special occasions, and multiple times I’ve found them difficult and sometimes a little painful to get back in. Why didn’t they heal correctly? Is there anything I can do?
