What are the reasons for bumps on the vulva?

Patient's question:

In the past few months, every time I have my period, I experience abdominal pain, excessive vaginal discharge, and a strong odor. A few days ago, I noticed a large, hard lump on my external genitalia, which seems to be a vaginal infection. I have tried many medications with no effect, and it is causing me great suffering.
What kind of help do I need: What could be the cause of the lump on my external genitalia?

Doctor's answer:

Vaginal itching with small bumps may be due to weakened immunity during the premenstrual period or caused by some gynecological inflammation.
