Question: I just noticed a small red line on my finger. I couldn't tell at first if it was a cut or a splinter. As I messed with it I noticed it was a tiny cut with an already formed scab. I picked the scab off while trying to be sure it wasn't a splinter and then I washed it with soap and running water, put on antibiotic ointment, and a bandaid. It is slightly alarming that I'm not really sure how, when, or where the cut happened. It looks as if it was probably a paper cut or from my skin being dry from washing often. I haven't been messing with dirt or anything really dirty besides the usual everyday things (grocery shopping, etc.) Is tetanus something I should be concerned with with this? I have not had a booster in over 10 years because I am sensitive to vaccines and have had reactions in the past. Is this XXXXXXX enough of a situation to require me to have a tetanus booster immediately?

Is it important that I go to the emergency room to get one now late at night or can I wait until the morning?
Also I have a cold or virus right now, would that matter?
