Being uncircumcised, and having had a fungal infection before, I assumed it was that. Started taking
Itraconazole, an oral anti fungal med, as well as applying clotrimazole, which is a cream. I did this for a week, and then spots just about disappeared. Two days later they were back, so I went to see a doctor. He said it appears to be fungal, prescribed Fluconazole, another anti fungal med, and I took those for 3 days, as well as continuing you with the cream.
