Went to my doctor because of my conch punch that I will probably get in 4-6 weeks (depends how soon the jewelry gets in..). My piercer advised to see if my doc would give me a preventive antibiotic since it's going to be punched at 8 mm. I knew my doctor was pretty easygoing with piercings but asking for meds that usually is only given when something is already infected was a bit of a stretch, or so I thought. Turned out my doctor was happy I was there and got that advise. He was more than willing to write me a recipe and said I should start one day before I get it punched and finish it after. And even though piercings really aren't his thing he is very curious to see how it looks ^^
I don't think I could have gotten a better doctor to be honest.
