Black Pimple-Like Thing

Patient: Hi, Well recently I had a pimple not within my ear canal but on the outside (not lobe) it was huge and sore so I gently popped it and cleaned it out with peroxide. Almost 2 weeks later, I notice exactly where the pimple was is now a big black bump. It’s not sore, or hot, nor a blackhead. Should I be concerned?
