You can always go get them swabbed right after they appear to be sure. I would suggest an IGG blood test now just to be sure of your status since so many people have it, but no recognizable symptoms. For example I wasn’t confirmed by blood test but no symptoms. Had a small Knick, cut type thing a couple weeks ago. It didn’t resemble anything like what you see or read about inline and no other symptoms. However I think this could be a reoccurring outbreak since I had the same thing months ago in the same spot. Without a confirmed test, could have gone years without knowing.
How long do they last? Has this been going on for years or something new that’s just happened?
