I was at my local park about 6-7 months back taking a walk, it was at night. As I was walking I kind of tripped and my sandals came off and I stumbled forward several feet. Either stumbling or looking for my sandals, I stepped on something sharp (felt a pain), I didn't see anything but it was very dark. I assumed it was a thorn as I was near the a woods edge and there was a lot of thorn plants close by. As I was walking, I would feel a sharp pain every time I would step on the injured foot, as if something was lodged in it. When I got home I discovered and pulled out a very tiny, hard piece of something. I wasn't worried at the time and discarded it quickly but from what I remember it was very small, maybe ~1mm or less in diameter, cylindrical and very short, like a 2-3mm in length (I remember cause it was hard to get ahold of with the tweezers). I don't remember it being very deep, and not a lot of blood, if any.
Now, I am worried at this point because I told a friend in passing conversation about this story and he seemed pretty concerned about it, but hes not a doctor or anything. So now, being somewhat of a hypochondriac, I am getting worried. I had no symptoms after that incident and the wound healed normally (no infection or residual pain after a day or so).
Should I be concerned about contamination from a dirty needle and catching HIV? (disease that scares me the most). I don't think a needle could break like that, just a very tiny piece off of the tip or something. I think I am overreacting.
I am not trying to mock this forum or HIV, I just don't know a lot about catching the disease from ramdon dirty needles and such.
Thank you everyone!
