I had gotten two sores inside my mouth swabbed while I had these symptoms. The fists sore appeared out of nowhere and I got it swabbed after getting it lasered to help with healing from my dentist— it came back HSV negative but I was also told it could be false negative since I lasered it.
Then I had a canker sore from a bite on my tongue swabbed about a week into it being there, and that also came back negative for HSV. And I was having these same symptoms on my lips then.
Should I go back and get my lips swabbed? There is no sore to swab but the tingling has not gone away.
