My dd has a quite a large verruca on her foot, we were told for a few years it would go away on its own but after around 4 years it’s just got bigger and more painful. She struggles walking on it for long periods of time especially when she is at work as she’s on her feet the whole time. She is always trying to walk on the side of her foot to avoid pressure on the verruca as it’s painful. We did speak to a pharmacist in who had a quick look at it and said that she doesn’t think any treatment will work only minor surgery due to how bad it is and the fact that nothing else has worked. We’ve tried duct tape which ended up giving her really red irritated skin, we tried different over the counter verruca products, filing it down every day, I’ve even been at it with a Stanley knife 
. Are there any miracle solutions any of you have used that you’d be willing to share? It’s so painful and she really wants to get rid of it
