You can most likely have a BBL despite having hidradenitis. I am for thighs with what you go through having hidradenitis.I can be a miserable condition.Most plastic surgeons will give antibiotics at the time of surgery and give patients anabiotics to take after your surgery.I suggest having several in person consultations with board-certified plastic surgeon's who specialize in this procedure.Best,Mats Hagstrom M.D.
