Swelling near labia minora. Pains a lot.

When was in  8th class, I discovered that my labia minora has elongated into some extra mass of cells , and then it wasn't painful at all , However year by year as the itching  started,  I observe the fact that this elongated part swells up after I harshly itch it. I had an appointment with a gyanecologist then but she said it was all normal with no big issue ,just a fungal infection for which she prescribed some medication. She said it was normal for a vagina to be like mine. However these days the itching has become way too severe and this lump of mass swells to an enormous size.  It feels like some fluid is inside of it . And after an hour or two it leaks certain fluid and returns to its normal shape. It's highly uncomfortable . It also pains a lot.
