Can herpes break out in blood blisters in multiple places inside your lip and on your cheek area or would there likely be another cause for that? I had 2 very noticable places (lumps) with one that busted & about 14 tiny blood spots in my mouth. With the larger ones, one was red, the other is black. My fatigue is also really bad. I've had outbreaks of cold sores on the outside of my lip for 20 yrs, but I've never had blood blisters in my mouth.
If this happens again, you might consider having them swabbed to confirm if they are in fact herpes.
