Please!! Any new ideas? My son has had verrucas (8 of them) for about 3 years and they do not go. He is getting depressed about them. I have tried many treatments, freezing, salicylic acid, teatree, dead sea salt baths, colloidal silver, etc.The doctors say it is his age and they may take some time,but 3 years and no improvement, in fact the opposite. The silver showed the best (slight) improvement but now getting worse again even with that. Please help!
