Welcome to the forum. Do not try tricks with needles yourself. It may make the bump worse. It can be a sweat bump, just a new hair or a cyst
. If it is a sweat bump and you stop fiddling with it , it will go away by itself in 3-5 days. Since you have already fiddled it should go away by a week.
If it does not go away by itself, you should see a gynecologist to get clinically examined to rule out bartholin's cyst. Keep hygienically clean, take antiseptic wash when you visit rest room.
If cyst is diagnosed its fluid should be sent for culture to rule out any STD
. Drink plenty of water, soups and juice. Keep well hydrated.
Have a nice day, take care.
