How To Treat Plantar Warts

Cryotherapy

Cryotherapy is a type of treatment that uses freezing medication. Since it's a more intensive treatment, it tends to be done in a doctor's office. A medical professional should administer the treatment to make sure it's done safely. During a cryotherapy treatment, the doctor will apply liquid nitrogen to the plantar wart by using a cotton swab or a spray. Liquid nitrogen can be very painful when it comes in contact with the skin, so the doctor may opt to numb the area beforehand. Liquid nitrogen leads to the formation of a blister around the wart. Within a week after the treatment, the dead tissue will slough off. Like prescription medications, cryotherapy can sometimes stimulate the immune system to help fight warts caused by viruses. The wart might not disappear completely after one treatment, but it will often diminish in size. Some patients need to have repeated treatments at a clinic over every two to four weeks until the wart fully goes away. Combining cryotherapy with salicylic acid might be more effective than cryotherapy alone, but there needs to be more research on this.
