Hello, I am 25 years old guy. For the past 10 days I am having rashes in my inner thighs and my testicles. My inner thighs and both the testicles have become red. I feel like scratching the area every time and after I do place becomes red and swells. I am applying Candid powder in the affected area but it hasn't helped me much. I feel like scratching the area and after that it pains. Please recommend me what can I do to get rid of this. Please suggest me some medicine to heal it.
