Foreign Body Lodged In My Scalp

Patient: Hello…I am desperate for a solution. I have this bb gun bullet thing stuck in my scalp just above my forehead. I am beginning to lose hair around the area. I would like to know a kind of doctor that could remove this foreign object from my scalp. I’ve had it since I was in middle school I believe, maybe 13. I am now 25. Any information would be a miracle.
