I just had two, but they had been there for years. They were just a normal buildup of cells, but to me they looked like permanent zits. I had "holes" afterward too, but they healed fine and you can't tell they used to be there. Just keep rubbing Neosporin on them several times a day.
Sorry I can't tell you more, but that's about it. They didn't come back.
I would think that either your regular doctor (my family physician did mine) or a dermatologist could freeze yours off since now you know they are benign. Insurance covered mine too. Seems to me it should be covered just like removing warts, which is also just a matter of freezing them off.
