Why do i keep getting boils all over my body it keep leaving ugly marks i have them on my breast also?

Furunculosis: This sounds like recurrent Staph aureus infections of the skin. It needs culture and sensitivity determination, treatment with antibiotics (possibly for a long while) and attempts to decontaminate your nose and throat using mupirocin ointment, and simultaneous use of a chlorhexidine containing soap to attempt to rid your skin of the same organism.

Need photos: If you are developing "boils" in the hair bearing areas i.e.axillas.groins,breasts, vulva and/or perineum you may have Hidradenitis Suppurativa which is a skin condition that affects apocrine sweat glands. You should be evaluated by a physician who will be able to make the correct diagnosis.
