Can pilar cysts have any symptoms/effects? - pilar cysts symptoms

I have a cyst on the back of the head column in the lower right corner. There seems to be very important, perhaps, 5 "(perhaps less?) Wide. Now my question is, symptoms, or it may have adverse effects on the motor / brain function / etc?

I always had headaches and they appear to come from the back of the head. It really feels like a cyst pressing against a specified time and pressure on them. I do not know if it's just my feeling, but is it possible?
