I used to have verrucas, I tried everything from boots(store) to remove the verrucas nothing seemed to work. until one day I'm travelling and I've bought some argan oil. I've randomly massaged the oil on my foot not taking much notice few days laters I noticed the verrucas started to look like they're disappearing and then I remembered how I saw goats in trees where these argan seeds grow after seeing my feet I remembered having heard there's not a single disease on earth which Allah has created a cure for except death. Maybe you should try some sort of natural oil. I'm not sure if argan oil will make it worse but there are other oils out there. Cut out sugar and drink 2l of water a day
