For the past 3 weeks my cartilage piercing has been infected. I had it pierced nearly a year ago and all was fine until it became very irritated, red, swollen and scar tissue began forming. For 8 days I've been taking cephalexin 500mg as prescribed. The doctor tried to drain the abscess today through a superficial incision, which did not work. I'm now using muciprocin ointment twice daily and the cephalxin is about to run out, and my ear is still infected. Is there anything else I can do?
