Post-Cryotherapy Concerns: Warts and Skin Reactions

Cryotherapy after wart treatment..?

Hello Doctor, I have a wart on the sole of my foot.
Last week, I underwent cryotherapy, and the area where the wart was has formed a scab.
However, a ring of swelling resembling a blister has appeared around it.
After walking a lot yesterday, I noticed that the previously clear area has turned red and dark.
I can't help but wonder if there is internal bleeding.
It was soft before, but today it has become hard.
I am very worried.
Is this situation normal? Should I return to the dermatologist for a follow-up immediately? Thank you for your response.

This is a normal reaction; you just need to return to the doctor for a follow-up appointment in one week.
Wishing you peace and may the love of Jesus be with you.

More Info

After undergoing cryotherapy for a wart on your foot, it’s understandable to have concerns about the healing process and any changes in the skin surrounding the treated area. Cryotherapy, which involves freezing the wart with liquid nitrogen, can lead to various skin reactions as part of the healing process.
Firstly, it’s common for the treated area to develop a scab as the skin heals. The formation of a scab is a natural part of the body’s healing response, as it protects the underlying tissue from infection and further injury. However, the appearance of swelling or a blister-like formation around the treated area can also occur. This may be due to the body’s inflammatory response to the cryotherapy, which can cause localized swelling and fluid accumulation.

The redness and darkening of the skin surrounding the wart, especially after increased activity such as walking, can be concerning. This could indicate several things:
1. Inflammation: The body may be responding to the trauma of the cryotherapy with inflammation, which can cause redness and swelling. This is typically a normal response, but it should be monitored.

2. Bruising: If the area has become red and black, it could suggest bruising, which may occur if there was some trauma to the area during or after the procedure. Bruising can happen if the skin is sensitive or if there was any pressure applied to the area.

3. Infection: While less common, there is a possibility of infection, especially if the area is painful, warm to the touch, or if there is any discharge. Signs of infection would warrant immediate medical attention.

4. Fluid Accumulation: The formation of a blister or fluid-filled area can be a normal reaction to cryotherapy. If the blister is intact, it’s generally best to leave it alone to allow it to heal naturally.

Given that you’ve noticed changes in the area, particularly the transition from soft to hard, it’s advisable to consult with a dermatologist. They can assess the area to determine if the changes are part of the normal healing process or if there’s a need for intervention.
In the meantime, here are some general care tips for post-cryotherapy:
- Keep the area clean: Gently wash the area with mild soap and water to prevent infection.

- Avoid picking or popping blisters: If a blister has formed, it’s best to leave it intact to protect the underlying skin.

- Monitor for signs of infection: Look for increased redness, warmth, swelling, or discharge.

- Limit activity: If walking exacerbates the symptoms, consider reducing activity to allow the area to heal.

In conclusion, while some swelling and discoloration can be normal after cryotherapy, it’s crucial to monitor the area closely. If you have any doubts about the healing process or if the symptoms worsen, seeking a follow-up appointment with your dermatologist is the best course of action. They can provide reassurance and appropriate treatment if necessary.
