Welcome to the forum. The symptoms are indicative of fungal infection in the groin area. It is nice to know that he has been tested negative for STD
. He should not be sexually actve till he has been treated. He needs to be examined clinically and get all required investigations done.
He can be suffering from sinus
in the scotum, that is causing the leakage ( other reasons can be hydrocoel ). Surgical intervention is needed for permanent cure. He can take fluconazole
after consultation for a week, antibiotics like ampilox
and atihistaminics can give symptomatic relief.
It will be better for him to take injectables in an emergency room for better results. Take care.
