Some warts disappear on their own over time, but different treatments can get rid of them -- such as burning or freezing the wart. Like any treatment, burning or freezing a wart has side effects. These side effects apply to common warts, not genital warts or plantar.
When a wart is frozen or burned off, there will be pain at the site of treatment. The pain is usually mild, so it's unlikely you'll be given an anesthetic for the procedure. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can be used to help with pain. Pain from the procedure can last up to a few hours; however, if a blister occurs, it can cause pain until it disappears.
Because of the irritation to the skin caused by treatment, a blister is likely to develop at the site. These blisters are mildly painful and disappear within a few days. To avoid further pain caused by the blister, use an adhesive bandage to protect it. It's best to leave the blister intact to help avoid infection. If you notice any signs of infection, such as pus or extra redness, contact your doctor.
Burning or freezing a wart kills the top layers of skin, so you'll see dead skin coming off the treatment site. This side effect should not cause pain, and the dead skin will fall off by itself.
Treatment causes temporary skin discoloration around the treatment site. Discoloration is caused by the extreme temperature that the skin is exposed to, whether from burning or freezing the wart off. You should expect redness around the treatment site. The skin will return to its normal hue within a few days.
