I am 13 years old and I​​​​​​​ have a lump on the side of my private area and I have visited the doctor and she said that it was healthy for a young girl to have that so I left it for a year but recently it has gone bigger and is starting to hurt. It does not look like a cyst or a pimple or anything like that and i'm scared if i may have to get surgery, someone please help if you may know what it might be. Thank you.
