I had a couple of blisters on my lip & a burning sensation in my mouth?



In 2015 I went to the obgyn because I had ulcerations on my vulva. Along with that – I had a couple of blisters on my lip & a burning sensation in my mouth & could only consume milk for a couple of weeks. The OBGYN did a swab test on the ulcers on my vulva for herpes as well as a blood test. Everything came back negative. I have had nothing similar since. 4 days ago I had oral/vaginal sex. A singular blister appeared on my lip 2 days after. There is nothing abnormal in my genital region. What could be going on?

Age: 31
Female
Medications: None
No
General Information: In 2015 the dr felt as if my issue was a complex yeast infection (oral sex, vaginal sex, then oral sex again). I visited the obgyn a month prior due to not having a period for 3 months. Within a span of a month I had the previously described sexual encounter & then started my period – which is when all my symptoms began. When I went for the swab test I also had 2 endocervical polyps removed that we did not know I had until my exam. Since then I have had no issues even remotely similar other than the removal of another polyp about a year ago. The sexual encounter 4 days ago was the same with the same person as before (oral, vaginal, oral, vaginal). Two days later is when the single blister appeared in the almost corner of my lip. No pain or anything. I’ve been monitoring my private area and there is nothing abnormal in that area thus far which makes me feel like it is isolated to my mouth.

Looks like Herpes. It may be possible that you had a false negative result. A DNA – Nucleic Acid Amplification Test (NAAT) is more accurate and should be done. Another possibility is an allergic reaction to your partner’s sperm, saliva etc..

Hi.
The blister can be due to bacterial infection too.
But the appearance is more like viral infection or Herpetic cold sore.
So once get a microscopy of the scraping from the sore done along with a Polymerase Chain Reaction and an Antibody test done to confirm the diagnosis.

Hope this helps..

Regards.
