DS 18 has a wart on the back of his hand. I have an appointment with a dermatologist on Tues to have it frozen off. Our co pay is about $15 but we may need a second visit and I KNOW we will be in the waiting room a long time. On the other hand there are wart removal products that use a similar freezing method, although probably not as cold as the liquid nitrogen for about the same cost as my co pay and it provides for multiple applications. Has anyone used this??
