Thanks for the query.
According to your description, the possibilities are :
- Genital infection
causing enlargement of the clitoris
-Bartholin cyst. Bartholin gland
opens at the inner side of the labia.
When the duct of the gland gets blocked it will form a cyst.
If the cyst gets infected abscess
You once consult gynecologist, get examined to find out the exact cause of the problem and take treatment accordingly.
