Hello,
Without examination,confirmation of a diagnosis is tough but it can be contact dermatitis,rash due to friction rub,folliculitis,cysts ,molluscum contagiosum(multiple, small, dome-shaped papules, often with a central depression or plug) or genital warts(caused by HPV infection).
Apply warm compresses,Neosporin ointment and calamine lotion and avoid messing with it.You can take anti-inflammatory pain killers like ibuprofen or acetaminophen.If the lumps persist then it will be best to get it evaluated from a dermatologist.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Did you get the yeast infection cream because your gynecologist said that you have a yeast infection? If you had the same symptoms when you saw him and he didn't find a yeast infection, there's very very little chance that you have one and you wouldn't get any good out of using the cream anyway. Also, if you do have one and the cream causes burning or pain, call and ask if your doctor wants to suggest a different cream or medicine. My doctor told me that the over the counter creams have lots of preservatives in them than they used to, and that her patients usually end up with more burning and pain after using them. So, she always gives prescriptions for better creams. There's also a pill to treat yeast infections, but it's sometimes not as effective; your doctor could decide about that. If all creams burn because of the skin condition (or just higher than normal sensitivity to creams), you could mention that and he might choose the pill option.
If your doctor didn't notice the bumps and other skin changes until you mentioned them, I'd be pretty confident that they aren't Herpes; that has a very particular appearance. A lot of things can cause little bumps, including skin irritation from yeast infections, menstrual pads (even if you've used the brand before), underwear (especially if it's new or not loose enough). I'm not too sure what to make of the fissures and cracks, honestly, or what diagnostic significance they could have. But I do know that skin irritation which causes bumps can cause other minor skin changes.
The bumps could possibly be genital warts caused by HPV. If they are, it's nothing to get overly concerned about unless your doctor says otherwise. It's very common and more people have had HPV than haven't. There are different types; some are visible, and others can't be seen. The ones you can't see are more dangerous than the ones you can. If they're warts, they'll probably go away within a few months after they showed up and probably not come back. You can get the actual warts-- and herpes lesions-- a long time after the time you caught the virus through sexual activity. If you aren't familiar with HPV, it would be a good thing to discuss with your doctor. There are ways to possibly catching it again. There's a vaccine you may wish to consider, if your doctor thinks it's a good idea. Condoms sometimes prevent it, but not always. It spreads from infected actively skin to uninfected skin, most commonly. Types which usually affect the mouth can also infect the genitals, and even the hands. So, there are many ways to catch it other than intercourse, unfortunately. I'm sorry; you're probably pretty grossed-out if you haven't heard much about HPV before!
