If it is a wart you can try this. I had a wart on the pad of one of my fingers and ran into an accidental cure! I had this wart for around 3 years, had tried to hack it out, freeze it, cover it. Nothing ever worked.
Here's what happened; I started using this lotion on my face once a day. I put a drop of it on my fingertips and rubbed my fingertips together to spread it, and then put it on my face once a day. Whatever excess there was on my hands I just rubbed into the skin. My wart disappeared in less than two weeks. I have had my Dad try this lotion for his warts on his fingers, the warts got smaller within 3 days! I use this lotion on my face because I have seborrhiac dermatitis and it does not burn when I put it on. I trialed a bunch of lotions for this reason.
The lotion is called, Fruit of the Earth Vitamin E Gentle Healing Skin Care Lotion. I got it at Walmart for less than $3. You can get it in a bottle or a little pot. The bottle stuff is a little thinner than the pot. It is in a white bottle with an orange or yellow cap. I've seen both. The pot is white with orange and yellow writing on it.
Somehow this lotion works for warts, I found this out unintentionally but it really does work. I think it must be because of the vitamin E, but whatever it is, it works, its cheap and its painless!
Hope this helps your daughter!
