What is the cause of a lump at the vaginal opening?

Patient's question:

No

Doctor's answer:

It is recommended to go to the hospital for a thorough examination before starting treatment, and do not use medication indiscriminately. Additionally, after using the toilet, remember to wipe from front to back. This is because the anus may carry a significant amount of bacteria, so avoid wiping from the anus to the vulva to reduce the risk of infection.
