NEED HELP WITH INFECTION...

ok, I have a decent amount of work done, close to about 60 hours or more worth....I GOT AN INFECTION, its only in a smaller part of the newest piece I got done...its where the red and black ink got mixed together...now I called the hospital, and they told me to keep cleaning it, I hadnt called the shop because today was the first day it looked a little bad...HOW CAN I TAKE CARE OF IT WITH NO MORE DAMAGE/INFECTION PROBLEMS??? like I said, its only in a two small parts, the rest of it is fine...anyone got any advice? I will call my shop tomorrow to let them know what happened...
