(Ask Cash Doc) I'm stressed because of flat warts.

Previously, I had a flat wart completely removed with a scalpel, but recently it has reappeared and become noticeable again.

The person who used to help me has quit, so I'm worried because there is no one left. The dermatology clinic is too crowded, and there are no female dermatologists. They say it's caused by immune system issues, but I wonder if anyone has naturally gotten rid of it. If it has disappeared, I would like to know the secret. ㅠ
