Your recurring boils on the labia are usually caused by blocked hair follicles or minor skin infections, so this is a common problem and not necessarily a sign of anything serious. Sweat, tight clothing, and shaving in that area can make it more likely to happen again.
Next Steps
Please see a gynaecologist in person if these keep recurring or turn large and painful, since an examination there will guide the right treatment for you.
Health Tips
Try not to squeeze or pick at them yourself, since that can push the infection deeper or leave scarring.
