Ouch my gauges are bleeding and swollen?

Two night ago i switched from a 2g to a 0g i havent skiped any sizes in my gauging but this one was the most painfull it hurt when i put it in but went in without much struggle, it swelled fast and hurt the next day it was swollen. today i noticed blood and liquid coming out of the hole although it dosnt hurt much anymore and is easy for me to twist around a little bit it is still very swollen.what do you guys recommend to help with the swelling again at the moment the pain is minimal
