Cryotherapy - Frostbite in the Wrong Area


Last year, during cryotherapy on the sole of my foot, the nurse accidentally froze the wrong area, which later developed a small blister.
It wasn't very painful, so I didn't pay much attention to it.
Recently, I noticed that the frozen area has turned into a small pit, and I can pull out some skin flakes from the center (but it doesn't have the visible blood vessels like a wart) and it hasn't healed on its own like the affected area did.
Should I see another dermatologist about this, or is it okay to leave it alone?

More Info


Cryotherapy is a common dermatological treatment used to remove abnormal skin lesions, such as warts, skin tags, and certain types of skin cancers. However, as with any medical procedure, there can be mistakes or complications, such as the one you experienced where the treatment was applied to the wrong area.
In your case, it seems that the area that was mistakenly treated has developed into a small pit, which is concerning. The presence of skin peeling and the fact that the area has not healed properly are signs that warrant further evaluation. While it may not be painful, the changes in the skin's texture and appearance suggest that the healing process has been disrupted, possibly due to the cryotherapy.

When to seek dermatological help after cryotherapy can depend on several factors:
1. Changes in Skin Texture: If you notice any changes in the texture of your skin, such as pits, bumps, or unusual peeling, it is advisable to consult a dermatologist. These changes could indicate scarring or other complications from the treatment.

2. Persistent Symptoms: If the area remains unchanged or worsens over time, it is important to seek medical advice. Skin that does not heal properly can lead to further complications, including infection or the development of new lesions.

3. Cosmetic Concerns: If the appearance of the skin is affecting your self-esteem or quality of life, it is worth discussing with a dermatologist. They can provide options for treatment or cosmetic procedures to improve the appearance of the affected area.

4. Signs of Infection: If you notice any signs of infection, such as increased redness, warmth, swelling, or discharge, you should seek medical attention immediately.

5. Uncertainty: If you are unsure about the changes in your skin or have any concerns about the treatment you received, it is always best to err on the side of caution and consult a dermatologist.

In your situation, since you have observed a persistent change in the skin where the cryotherapy was applied, it would be prudent to seek a second opinion from a dermatologist. They can assess the area, determine if there are any underlying issues, and recommend appropriate treatment options. This could include topical treatments, further evaluation of the skin's condition, or even referral to a specialist if necessary.

Additionally, it’s important to keep in mind that skin healing can vary significantly from person to person. Factors such as skin type, age, and overall health can influence how well and how quickly your skin heals after a procedure like cryotherapy.
In conclusion, while it may be tempting to ignore the changes in your skin, it is always better to seek professional advice when it comes to skin health. A dermatologist can provide you with the reassurance and treatment you need to ensure your skin heals properly and to address any cosmetic concerns you may have.

Cryotherapy can potentially lead to scarring, and it may not always be avoidable. The actual situation depends on the specific case; if there are atrophic scars, fractional laser treatment can be used.
