The best way to know is to get tested specifically for HSV. I had the same thing a year sgo, just one sore. Looked like a pimple really. But went to my physician to get her opinion. She said it ‘didn’t look like herpes’ and ‘not to worry about it, it was very common’.
I said, ‘I’d still like to be tested.’
I was surprised because just two months earlier during my annual physical I had been tested for STD’s as part of the health screening. Lo & behold, as it turns out, their STD screening (which came back negative) doesn’t include testing for herpes. Isn’t that crazy?
Anyhow, I would suggest getting tested for your own piece of mind and your own knowledge!
