Why do i get hard painful fillef bumps arund my panty lines

Hello. Thank you for your message.

It might be vaginal acne. Vaginal acne (bikini bumps) is a skin condition that is typically caused by a change in your hair follicles and sebaceous glands. Although a fairly common condition among women, vaginal acne can be irritating, embarrassing and uncomfortable. Shaving can sometimes cause this.
