Scrotal skin issue, help

Hello, I have been discovered with mycoplasma genitalium took 21 days of levofloxacin. 2 weeks after something appeared on my scrotum.
I would apreciate any help if anyone has something similar. Tomorrow I am going to be tested for hiv..

what were the results?

Could be any number of things, especially with the use of abx for 21 days, something like yeast but could also be shaving/trimming related
