Q: Managing Plantar Warts: Post-Cryotherapy Care and Common Concerns

Treatment for plantar warts may involve cryotherapy, which can lead to the formation of blisters. After the procedure, proper aftercare is essential. Here are some recommended aftercare methods: 1. Keep the area clean and dry: Gently wash the treated area with mild soap and water, then pat it dry with a clean towel. 2?

I recently visited a dermatologist for warts on my hands and feet.
During the cryotherapy session, the doctor sprayed a large amount of liquid nitrogen on the warts.
The next day, I woke up to find a large blister on my foot, about the size of half a thumbnail.
I'm unsure what to do, so I have a few questions:
1.
Should I puncture the blister to drain it?
2.
Since warts are caused by a virus, is there a risk that the fluid from the blister could spread the virus to other areas?
3.
The doctor mentioned that the black spots on my hand are all warts and treated them with cryotherapy, but during previous examinations of my hands, I was not informed about them.
Is it normal to discover two or three additional warts all at once?
4.
My foot warts have recurred two or three times in the same location, and each time the doctor said they were healed.
Is this situation typical? I'm worried about recurrence and the need for another treatment.
5.
If I return for a follow-up and the doctor is unsure whether the warts are completely gone, can I request another round of cryotherapy on the affected area to ensure the warts are eliminated? (For example, if there are no visible black spots but the wound seems to still be present.)
6.
Are there any specific care or precautions I should take for warts on my hands and plantar warts?

If the blister is large and painful, you can return to the clinic for the physician to assist with incision and drainage.
2.
There is a possibility, but it is not guaranteed.
3.
Generally, viral warts have a latency period of several months before they form visible lesions, so it is possible that they were still in the incubation period during previous examinations.
4.
Recurring outbreaks may be due to residual viral particles that are not visible to the naked eye remaining in the skin.
After complete treatment, an additional cryotherapy session can be performed to reduce the chance of recurrence.
5.
You can communicate and discuss with your outpatient physician.
6.
Keep the skin on your hands and feet dry and breathable; during the autumn and winter seasons, you can use hand and foot creams.
If the skin lesions do not improve or worsen, it is advisable to consult a nearby dermatologist for diagnosis and treatment at http://www.derma.org.tw/user_finddoctor.php.

More Info

Managing plantar warts, especially after cryotherapy, can be a bit challenging, and it's understandable to have concerns following treatment. Let's address your questions one by one, while also providing some additional context about plantar warts and their management.

1. Should I pop the blister?
Generally, it is not advisable to pop blisters that form after cryotherapy. Blisters serve as a protective barrier for the underlying skin and help prevent infection. If the blister is large and painful, you can gently drain it by cleaning the area with soap and water, sterilizing a needle, and puncturing the blister at its edge to allow fluid to escape. However, do not remove the skin flap, as it protects the underlying tissue. If you notice signs of infection (increased redness, warmth, pus), consult your healthcare provider.

2. Will the virus spread if the blister fluid moves?
Plantar warts are caused by the human papillomavirus (HPV), which is typically localized to the wart itself. The fluid in a blister is not known to contain the virus, and it is unlikely that it would spread to other areas of your body. However, it’s always a good idea to keep the area clean and avoid touching other parts of your skin after handling the blister.

3. Is it normal to discover multiple warts during treatment?
Yes, it is not uncommon for dermatologists to discover multiple warts during treatment, especially if they are not visible at first glance. Warts can sometimes be small or hidden, and a thorough examination may reveal more than initially thought. If you have a history of warts, it’s possible that new ones can develop over time.

4. Is it normal for warts to recur in the same spot?
Recurrence of plantar warts in the same location is common. The HPV can remain dormant in the skin, and if the immune response is not strong enough to eliminate the virus completely, warts can reappear. It’s important to follow up with your dermatologist if you notice any signs of recurrence.

5. Can I request additional cryotherapy if I’m unsure if the wart is completely gone?
Yes, if you are uncertain about whether the wart has been completely treated, you can discuss this with your dermatologist during your follow-up appointment. They may recommend additional cryotherapy or other treatments to ensure that the wart is fully eradicated. It’s important to communicate your concerns clearly so that your doctor can provide the best care.

6. What care should I take for hand and foot warts?
For both hand and foot warts, maintaining good hygiene is crucial. Avoid picking at warts, as this can lead to spreading the virus. Keep the affected areas clean and dry, and consider using protective footwear in public places to prevent the spread of warts. If you have plantar warts, using cushioned pads can help relieve pressure while walking. Additionally, boosting your immune system through a healthy diet, regular exercise, and adequate sleep can help your body fight off the virus.

In summary, managing plantar warts after cryotherapy involves careful attention to any blisters that form, understanding the nature of the virus, and maintaining good hygiene. If you have ongoing concerns or experience recurrence, don’t hesitate to reach out to your dermatologist for further evaluation and treatment options.
