Nipple piercing not healing even after removing ring - advice?

I had my nipples pierced a year ago. I took them out because they got really badly infected. Took antibotics for 5 to 6 weeks and it is still bad. I have met with a general surgeon. He is suggesting I see a plastic surgeon. My left nipple hurt very bad if I do not pop it and it comes out with white/yellow stuff. It comes from where the piercing was. Is there something else I can try? I am sc meeting with an actual plastic surgeon about surgery due to the fact it is only getting worse.
