How large are the blisters supposed to swell after burning warts?

Post treatment : Hello, your health care provider can only answer that question. Some things that are important to understand is that everyone heals differently. Also some locations are more reactive to the procedure than others. Finally, the degree of energy used to “burn your warts” is probably the most important factor related to blister size. Make sure you stay in communication with your surgeon.

Can be large : Up to an inch, maybe even more. If the area turns very painful or very red, get seen

Cryosurgery : It should only be a millimeter outside the limits of the lesion. However if more freezing is used the burning may be greater
