Can Arm Trauma Caused By Pencil Stabbing Have Any Long Term Effects?

I was stabbed in the arm with a pencil over ten years ago. It healed up and I never had any issues. All I remember at the time was going to the school nurse who told me I was fine since pencils were not made of lead anymore. I am obsessing over this now for some reason and I am concerned that it might lead to future health problems. The 'graphite tattoo' doesn't bother me, just the long term effects. Please help.
