Hollow needle, if you're going to do it yourself.
where to obtain one, good Q.
I've um...found them at doctors offices before, and in some states you can find them at farm-supply type stores in the veterinary type sections.

and no matter how/where you get it done, for piercing aftercare I've had luck cleaning with Hibiclens and applying Neosporin.

I do suggest you go the professional route tho.
