Help! Cyst That Won't Go Away?

I got what my dermatologist said was a cyst "removed" by him using an electric needle to "pop" it. It turned into a little scab which fell off 4 days later, but under the scab it was still pinkish red and it was still a bit raised, much less so than before but it was still raise and colored. Now, there is what seems like a tiny tiny indent in between the bump. I can best describe it as looking like a butt chin, it goes up then down then back up. What the heck is on my face!?
