If the scrotum often has local inflammation of the follicles, manifesting as local redness, swelling and heat, it is often caused by local uncleanliness. It is recommended to keep the vulva clean, preferably with warm water 1-2 times a day, and do not wear tight underwear or outer pants, which affects local blood circulation and can also lead to local inflammation of the hair follicle. It is best to use cotton sanitary napkins when you are menstruating to ensure good local ventilation and also to avoid inflammation. Once the hair follicle inflammation occurs in the vulva, it is advisable to shave off the local pubic hair and apply Bactrim or Erythromycin ointment to the area for treatment. The actual fact is that you should not eat fried food and do not eat spicy and sour food.
