<s>[INST] I am 29, unmarried female.I have never had sex. I have experienced a lump like structure right at bottom of vulva opening (pls note i mean to say it is right in front and at bottom base). It doesnt hurt nor itches. The only concern is it grows in size during periods and then shrinks back. Lately i have also noticed more white discharge which at times is slight lime in color.i get my periods regularly, rarely get cramps. I have got my USG done for lower abdomen and reports are normal.I am physically active and exercise with ease. I am very worried. Pls advise [/INST] Hi.This is definitely a cyst or a mass which has a control by hormonal changes. IT is better be excised in toto and get a histopathology reporting done to see what it is. TH white discharge may be due to vulvovaginitis and can be easily cured by appropriate antibiotics and metronidazole. </s>
