I am targeting my yeast/fungal infection at the moment. I never got it diagnosed by a doctor, so take what I say with that in mind.
I had a Dry and flakey scrotum for about three weeks, and then one day I woke up with white opaque-ish stuff on it. I washed it off and it was gone. A few days later it came back, and then like two days after that a red non itchy bump appeared. So I bought an antifungal (Lotrimin Ultra), and have been using it for the last 5 days. I have seen a massive improvement. I still have another week of treatment, so it is not totally gone (I would say 100% of the dryness and scaliness is gone, and about 90% of the white opaque stuff is gone). Also, the bump is way less red, and is going down. Nothing for me was itchy nor did I have a full on rash. I don't have a foreskin, so that may lead to our different symptoms.
I would say that if you have not seen an improvement through an antifungal, try a different one or it probably is not a yeast/type of fungal infection.
