Edema on the pubic

Hello. Last night noticed the swelling of the pubis, until tonight the edema did not sleep. What can this be and what to do? Periodically, there are vaginal discharge white curdled with the help of transparent mucus, recently pulling the lower abdomen as with menstruation, there is itching in the intimate zone (perhaps from a razor) and itching in the anus (sometimes there as it were "wet"), I use tampons, sexual life I do not live. Can masturbation somehow cause edema? Thank you in advance.

In the near future specialists of our clinic will answer the question.
