A small number of patients with flat warts can heal on their own. The disease is viral and a large percentage of viral diseases in medicine are self-healing. For example, the flu is a viral disease that can heal naturally in about 7-8 days, and this does exist with flat warts. When the resistance is strong and the number of viruses is small or not very virulent, there is a possibility of self-healing. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. It is true that many patients are cured by themselves without treatment because their own resistance has increased. If you don’t pay attention to the progress, you may get more and more warts and bigger and bigger, starting with 1-2 warts, then developing to the whole face, then to the back of the hand, the upper arm, or even the whole body.
