When I was 11/12 year of age I mistakenly stabbed myself with a pencil. Today I'm 41 years of age and I have serious neurological problems. Could the pencil lead
to cause symptoms many years later.Basophilic stippling of the blood cells,and gum lesions with bluish discoloration would help in arriving at a diagnosis,apart from blood lead
to it. Yes, you will get a "tattoo" from the graphite but mine has been there for over 40 years and there is no problem related to it. I also have one in the roof of my mouth (don't ask!) but it's again no problem!
