Last week I developed common warts, and recently I noticed many black dots inside them. What does it mean when there are many black dots in common warts?

This condition should occur as a result of blood vessel rupture. Warts can disappear naturally, but they are contagious and can be transmitted to other locations. Treatment under a doctor's guidance—such as laser therapy or cryotherapy—can help manage them, although these procedures may inadvertently spread the virus to other areas. During treatment, maintain personal hygiene, avoid contact with contaminated environments or food, and limit consumption of spicy and irritating foods.
