Itching and pain in the vulvar area, with a bad odor, and blood spots when wiped. What's going on?

Patient's question:

Five days ago, I felt itchy and painful in the groin area, with a bad odor. When I wiped it, there were blood spots, but I haven't gone to the doctor yet.

Doctor's answer:

Eat less irritating foods
Avoid excessive vaginal cleaning
Maintain a positive mood
Clothing choices: Wear pure cotton underwear because pure cotton underwear helps with vaginal ventilation. Since most inflammatory bacteria are Gram-negative anaerobic bacteria that dislike oxygen, pure cotton underwear allows for ventilation and brings oxygen, which can prevent the occurrence of vaginal infections. Avoid wearing tight or non-ventilated jeans as outerwear to prevent worsening vaginal ventilation.
