I am diabetic using an
insulin pen (not a syringe). A few hours after I started the treatment, I gave myself an
insulin injection. I was traveling and didn't have a new needle, so I used the one I used before and left on the pen. It was more than 4 hours that i used this old needle on my insulin pen. Sorry, that was stupid. Say I was actually infected, would that mean I am having a 2nd exposure by my own possible infected blood, thus ruining my PEP?
