We see this question every few months on TB: "What should I do about my finger blisters?" Here's what Consumer Reports recommends: (you KNOW better than CR? Maybe... just show us your evidence) "If a small blister forms a few hours after your injury, leave it alone. That natural bandage helps guard against infection. Touching or puncturing the blister makes the burn more vulnerable to germs, even if it’s covered by a bandage. But if the blister is bigger than your thumbnail, go to an urgent care clinic or emergency room." Contrary opinions are very welcome... if they're supported with evidence; sorry, I'm just a hard ass that way; I want evidence, not your one-off story.
