Cryotherapy for corns and laser treatment for corns both produce significant pain, and depending on the degree of pain felt by the individual, the response to the treatment will be different, making it impossible to clearly compare the degree of pain produced by the two. Cryotherapy for corns is mainly carried out using liquid nitrogen, which can reach a temperature of about -196°C. The use of low temperature causes edema and necrosis of the muscle tissue at the corns, and inflammation of the tissue makes the pain more pronounced, while the low temperature of -196°C also produces severe pain when it touches the skin. The laser treatment of corns is generally selected for carbon dioxide laser irradiation, treatment for the vaporization process, will produce significant pain, generally need to use anesthesia before treatment. However, at the end of the treatment, the anesthetic effect is eliminated, which also produces a more intense pain. Therefore, both cryotherapy and laser treatment can produce stronger pain. Clinically, you can choose cryotherapy, laser treatment or other treatment methods according to the severity of corns and the doctor’s recommendation. Corns are prone to recurrence after healing. If you find that the corns are thickened, you can soften the corns with hot water and repeatedly wipe the affected area with a towel or pumice stone to reduce the chance of corns forming. Patients who suffer from bunions, or those with bony growths, need to promptly improve foot deformities to reduce the triggers for corns formation.
