Should I get foreign matter extracted from my body?

Strange Untold Stories of a tick in my head.. So I have a tick head inside my head because I ripped a ticks body off its head while it was biting MY head about 10 years ago. I was too creeped out to do anything about it and well sometimes it hurts, maybe due to I mess with it. And its still a lump and just quite gross. I tried to have someone knowledgable and sterilly (sp?) cut it out of my head for me sometime within the last year and they said it was too deep to come out. Some blood and pus does come out.

What is the process if I got this extracted? What would it even fall under? Do I go to the ER or ???? I do have health insurance but I don't know how to even look into this because its so so sooooo oddball. To be honest, I'm not sure if I need it out, its a part of me now. It doesn't seem to pose any serious threat but this is why I ask. Thanks for your help. Yes I was a dumb kid, hopefully I don't continue on to be a dumb adult.
