You can't edit it to include the link, but you can respond with the link.
Honestly, it could be a lot of different things - an infected hair follicle, a Bartholin's Cyst (depending on the location), a sebaceous cyst. It could be a herpes blister, but given that there's just one and you describe it more as a bump and not a blister, I'd not think herpes as the first choice.
HPV/genital warts aren't fluid filled, and syphilis causes a round, open sore, not a bump.
You're going to need to see a doctor to get this diagnosed. Even with a photo, it would be hard to tell online. It may require some cultures or biopsies to determine what is causing it (that's not fun but not as bad as it sounds).
Let us know what happens.
thank you for responding. here's a link. not sure it'll work.
i do have an appointment with my primary tomorrow, but am still stressing out quite a bit.
That looks more blood filled to me than dark gray, but honestly, that could be the difference in computer screens. That's why it's so important to have your doctor see it in person.
It doesn't look like typical herpes, either.
I wish I had something more definitive. DON'T squeeze it or try to pop it or put anything on it before your appt tomorrow. That could affect any testing they do. I know it's hard, but just let it be.
If the doctor thinks it's herpes, make them do a type specific culture or PCR swab on it (the PCR swab is better). Don't let them visually diagnose you. It's wrong as often as it is right. If they think it's bacterial in nature, ask them if culturing it for the specific bacteria would be helpful. This can help if you need an antibiotic to know which antibiotic you need. It's called a culture and sensitivity - the sensitivity tells them which antibiotics it will respond to.
Let me know what happens, and hang in there. If it's herpes, we'll get you through it, okay?
so far the physical exam is totally clear. she says that's a sebaceous cyst. there are no sores, no other lesions, no rashes, no skin abnormalities, no reason for concern. "normal anatomy for age" is the verdict.
