Its interesting to know that you are sure its not an std
Possible causes could include a folliculitis
or a bartholin
Folliculitis is an inflamation of a hair follicle which is usually
bacterial in origin and can progress to pus formation. This
is common following shaving or traumatic lesions on the ge-
develops when the drainage of the gland is
blocked leading to accumulation of fluid in the gland that
produces pain and might become infected to form an abscess.
Drainage of bartholin abscess
is done in a special technique
known as marsupialisation to prevent re-occurrence. However,
pus fill cavities should be drained.
Thus, it is necessary to see a doctor to rule out the possibility of
a bartholin abscess. If its not a bartholin abscess, normal wound
dressing after incision and drainage
Hope this helps you
