Recurring bumps on the vulva are usually from ingrown hairs, blocked skin glands or mild folliculitis. Tight underwear, shaving and sweating in that area are the most common triggers.
Next Steps
Switch to loose cotton underwear and avoid tight leggings for long stretches. If shaving or waxing seems to trigger it, try trimming instead. A mild, fragrance-free wash and keeping the area dry also help.
Health Tips
If the bumps turn painful, keep returning in the same spot, or start draining, please see a gynaecologist for a proper look.
