I have been having health problems for 8 or 9 years now. I won't bore you with all the details, but here is a link to the thread if you want to look
Anyway, last night I was sat thinking about what could be wrong with me and I suddenly remembered when I was about 10 or 11 some boy in my class stabbed me in the leg with a pencil and the end broke off. I could see this bit of lead travelling down my leg and I tried to stop it by putting pressure next to it with a ruler, but in the end I lost it.
Is this something to worry about?
