Post-Cryotherapy: Blisters and Bruising After Wart Treatment - Dermatology

More Info

---

After undergoing cryotherapy for the treatment of warts, it is not uncommon to experience some side effects such as blisters and bruising. Cryotherapy works by freezing the wart tissue, which causes the cells to die and eventually fall off. This process can lead to localized inflammation and tissue damage, resulting in the formation of blisters and discoloration of the skin.

In your case, the appearance of blisters after a week and two days post-treatment is a typical response to cryotherapy. The blisters are a result of the skin's reaction to the freezing process, and they serve as a protective barrier while the underlying tissue heals. The fact that the blisters are starting to shrink is a positive sign, indicating that the healing process is underway.

The deepening color of the blisters, turning to a reddish or purplish hue, can be attributed to bruising. This occurs when small blood vessels are damaged during the freezing process, leading to localized bleeding under the skin. This discoloration is generally temporary and should gradually fade as the area heals. However, if the bruising is accompanied by severe pain, increased swelling, or signs of infection (such as pus or fever), it would be advisable to seek medical attention.

The strange sensation you are experiencing when touching the area is also not unusual. After cryotherapy, the nerve endings in the treated area may be more sensitive as they recover from the trauma of the freezing. This heightened sensitivity can lead to unusual sensations, which should subside as the skin heals.

In summary, the symptoms you are experiencing—blisters, bruising, and altered sensations—are generally normal after cryotherapy for warts. It is essential to keep the area clean and protected to prevent infection. If you notice any concerning changes or if your symptoms worsen, do not hesitate to contact your healthcare provider for further evaluation and guidance. They can provide you with specific advice tailored to your situation and ensure that your recovery progresses smoothly.
