Cold sore caused by a drop of anesthesia?!

Question: Cold sore caused by a drop of anesthesia?

So today i went in to the dentists office for a root canal. (part 2 of 3 longgg appointments). I was really numb since the dentist is also a real good anesthesiologist (is that the right term?), well i was extremely numb, couldnt feel the drilling whatsoever just the small vibrations traveling through my jaw. well someone along the procedure he pulled out the big anesthesia needle (has a loop and all this cool looking stuff) and a drop of the anesthesia hit my lip, i could tell by the awful taste. well i just felt it drop since i felt the wetness on my chin a while after. well on my way home i noticed i had developed a huge coldsore like bump/bubble on my lip.
so is it possibly that anesthesia could cause this? because smy dad said it was possible.
help please

Answers:

Cold sores are caused by a certain strain of the herpes virus. Dont get grossed out or alarmed because a very large amount of the population carries the herpes virus in this form.

Outbreaks can be triggered by such things as stress, extreme temperatures, abrasions, and so forth. It might be that the anesthesia irritated your lip a bit and caused an outbreak.

If I remember correctly, the virus basically is always looking for a place to exit your lip. When something of this sort happens and weakens the area, it forms the blister.

However, it may be a different type of blister. If you've had cold sores on your lip before, it is probably the same thing and just caused an outbreak.

I'm a medic. I get cold sores.

Cold sores are latent viruses that come and go from time to time. It is not uncommon for cold sores to come up following dental appointments. The reason is due to the anxiety and stress of the appointment, not by the procedure itself.
