My 13 year old has a giant verruca under her heel. It's really painful to walk on and as a consequence she's not walking anywhere (she winces every time she puts weight on it). She's has 3 cryotherapy sessions but no improvement. She's also leaving duct tape on it most of the time. It's actually really upsetting seeing her in so much pain all the time. Anyone any ideas what to try next? I see needling and chemical type treatments on line. I'm happy to spend money to resolve this. She's actually begged us to get it cut out but I don't think that's an option any more. Thus far her GP has been treating her but I will bring her elsewhere. Thanks
