Sorry - but i have to agree with the crowd....have the doctor look. Puncture wounds are the most likely to get infected because "germs" get pushed down inside - and also they take the longest to heal. Staff can be found everywhere !! Not trying to be a doom-sayer or to scare you -- but in this case -given where and how you did this -- it's just best to be safe -- and a tetanis booster if you need one is always a good idea anyway. We all just want you to be ok.
