Plantar warts that grow back after being frozen can be treated again by freezing, or by surgery, laser or medication. Plantar warts are caused by a human papilloma virus infection, which is contagious and can recur as long as the virus is present in the body. When a plantar wart grows back after cryotherapy, it can be treated again with liquid nitrogen freezing, which often requires multiple treatments. In addition, reoccurring plantar warts can be treated by surgical excision or removed by laser or electrocoagulation. They can also be treated with salicylic acid, fluorouracil ointment, imiquimod ointment, paxillin, bleomycin and other medications under the guidance of a medical professional. The recurrence of plantar warts is recommended to go to the hospital in time for follow-up, under the guidance of the doctor for symptomatic treatment, do not self-medication.
