I know this post is somewhat old, but I just wanted to reply with saying that I am having the same symptoms too. About 17 days after me giving oral sex to a male, I showed three red areas form at the tip of my tongue, with sometimes a white substance around them as well. They did not hurt and lasted 3 days. About a month later, they showed up again at the same spots, no pain. A week from that date, it showed up a third time, same spots though this time I went to the doc that same day and he said it was a "stress ulcer" but that he could not rule out herpes since i told him about oral sex....but he didn't think it was herpes in his opinion. THough, the next day, my gums got swollen, as well as my tongue...but the sores were still in the same spot so no extra sores anywhere. This lasted about 8 days this time, accompanied by a bad headache three of the days, which I believe to be from stressing out over this. There were no swollen lymph nodes either. Also, my eyes burned whenever they got wet during thsi time, which I believed I moved this virus to my eyes when I put my contacts in. Went to the eye dr two days later who told me she did not see anything like lesions or herpes in my eyes but that she saw two dry spots which was probably from the contacts or maybe me scraping my eye with my nails. The eye burning lasted 10 days. The sores went away but kept coming back throughout the month...and the sores "spread" to the sides of the tongue as well.
I was also tested for herpes at 9/10 weeks post exposure....which came out negative. I'm wondering if this was a false negative or if this really is herpes. Has anybody been cultured to see if their symptoms were herpes in the mouth or have any other information about this? Also, a sidenote, I do have ulcerative colitis which my family has been telling me the sores are from this...but i'm not sure since they never happened before and I've had this disease for three years already.
