Lucky for you guys I saw this. I have the solution.
I've had three of these before (started spreading) on the ball of my foot. I've tried liquid nitrogen treatment and it was fucking painful. It came back after a few months. After that I had it surgically removed. The pain of that numbing needle punching through your foot callus is excruciating.
Zombie wart is back again after a few months. At this point I'm done trying to get rid of this and figured I would just deal with it. I mean, if surgery can't fix it then wtf else can I do right?
Then it dawned on me, when removing it surgically or by quick kill treatments, it doesn't always get the core or roots that might linger. So what better way than to let your own body get rid of it by letting your own skin push it out.
This is what I used

I would apply a thin layer after shower and would soak my foot for a few minutes in warm water and re-apply at night.
I used two of these and was able to get rid of my pw. After years of trying different things this one worked. My son ended up getting one about a year ago and I used the same thing on his foot and it worked again.
I suggest you guys try this. It worked for both of us. It kills the top layer so your body pushes new skin from underneath...this pushes the hpv out and is killed by the gel.
The best part is...it's painless. Yes it will take 3-6 months, but it works.
