I also have this..Mainly on my lower abdomen and The crease of my thighs and groing area..It has left nasty dark scars..Is there anything I can do?
Folliculitis ("blocked pores") often affects the groin. Preventing this is difficult. If she pops and squeezes the lesions, she ought to stop. If they are painful as you describe, she ought to consult a dermatologist, who can evaluate the condition. Potential remedies include antibacterial cleansing and antibiotic creams and tablets (for short periods.) Folliculitis is not contagious. Once it is inactive, the pigmentation it causes gradualyy subsides.
Best.
