The probable is the baby oil
Hi -
This could be a reaction to the baby oil, for sure. It could be from where you scratched, too.
It could also be herpes, even though your partner thinks he doesn't have it. Most people who have it don't know they do. Also, if he has oral herpes - and many people do even if they've never had a cold sore - he could give that to you via oral sex.
This blood test is going to be a baseline test. It's too soon for you to know via a blood test if this is herpes or not. It's a shame your doctor didn't culture it, but given that you had the sore as long as you did, I can understand (she should have tried, though). If it is something bacterial in nature, you'll need treatment for that, too.
If your herpes test is negative, get another test in about 3 or 4 months. Make sure it's a type-specific IgG test. If your doctor did an IgM test, disregard it, even if it's positive. It's totally unreliable. (Your doctor may not know this - so many don't.)
If it's positive, it's from an existing infection. If it's not typed, and comes back as hsv positive, ask them to do a type specific test so you know which you have. If it comes back as type 1, get another test in 3-4 months to see if you have type 2.
Ask your partner to get tested too. If he is negative, and hasn't had any recent partners, that will eliminate all of this.
I know it's so hard to wait, and it's scary. If it is herpes, I promise you it isn't as bad as anything you are thinking. Check out the Herpes Handbook at https://westoverheights.com/herpes/the-updated-herpes-handbook/ if you want. At least check out the testing section so you know what to ask for.
I hope you feel better soon!
