What should I do if I have common warts on my hands?

When suffering from common warts on the hands, the following measures can be taken for treatment: 1. **Medication**: Topical medications such as podophyllotoxin tincture and 5-fluorouracil ointment can effectively treat common warts. These medications work by exerting antiviral effects, enhancing local immunity, or dissolving the keratin layer, thereby causing necrosis and shedding of the wart tissue. 2. **Physical Therapy**: Liquid nitrogen cryotherapy and laser therapy are commonly used physical treatments. Liquid nitrogen freezing causes necrosis and shedding of wart tissue through low-temperature action, while laser therapy removes warts by laser ablation. 3. **Surgical Treatment**: When common warts are large in size and medication or physical treatments are ineffective, surgical excision may be considered. 4. **Preventive Measures**: During treatment and after recovery, it is important to maintain personal hygiene, avoid sharing personal items with others, strengthen immunity, and prevent recurrence and transmission. When suffering from common warts on the hands, appropriate treatment methods should be selected based on individual circumstances, and precautions should be taken to prevent recurrence and transmission.
