Fever Blister Vs. Cold Sore
What is a fever blister exactly? The answer might surprise you – it’s simply a cold sore. A fever blister and a cold sore are one and the same. If you’ve ever had a blister on your lip, chances are it’s a result of the herpes simplex virus and your fever blister was in fact a cold sore.
So why the confusion? Cold sores have been called fever blisters in the past because they often appeared when someone had a fever. But fever blisters are caused by the exact same virus as cold sores, because they are the same thing.
