Welcome to HCM!
I have gone through the question carrefully and from that it looks that you have a skin allergy/ some infection over genitals, it itches a lot, and you donot want to see the doctor for examination.
Form my clinical experience I can say that you need to take a course of antibiotic: cephalosporins should be helpful, twice a day, with cetrizine/ fexofenadine
, for itch, taken once a day, and diclofenac
sodium 50 mg for pain.
If you are sexually active, the treatment is also recommended for the partner, as it can be infectious.
It will help to keep the area dry and donot scratch it. Using mycoderm powder locally will also help it in resolving.
Hope the reply helps you
