I would go back to the doctor... I don't think they are warts, but they don't really look like a rash either...but then again, I'm just some person on a health forum. You should consider getting tested for other STDs, such as gonorrhea. However, hopefully this is just something totally benign.
I think the smallish whiter ones are Fordyce spots, which nearly everyone has, but in one of your pictures, there was a large red bump that I find a little curious and believe ought to be checked out by a doctor. It was a little harder to tell with the other pictures, but I think your best bet is to go back to the doctor and get tested for all STDs. Get the doctor's opinion.
The bigger red one was the one that was bigger than the others. It does not normally look that bad as i was trying to pop it before i took the picture and also am stretching out my skin. When my scrotum is just haning it doesnt appear to be that much different than the small white ones all around. it was just a little bigger and i got paranoid and started to try and pop it.
Hmm... well, maybe all of this is totally normal and picking at the one made it red and irritated. Maybe it was actually a vein or something that bulged out a bit and squeezing the skin covering it made it become irritated/mildly infected. If I were in your position, I would go to the doctor if it gets worse. I think an STD test would be a good idea anyways; anyone who is sexually active ought to get one, you know? Who knows. This might be some kind of allergic reaction to whatever you were given for the yeast infection (I am not sure if you have a cream or if you have oral medication...). I'd just watch how it progresses, and if it gets notably worse, get it checked out by the professionals. If seeing a doctor isn't possible, maybe try a doctor forum on this site. That way you can get a certified medical professional's opinion.
