Sounds like what the pediatrician used on Moon Unit last year after her single wart turned into 4 (2 per hand). They wound up doing only 3 of the 4 warts because the treatment hurt.
Worked pretty well - the warts disappeared w/in the month. Oddly, even the untreated one did, as did the one I caught from her
So my advice is: get someone else in your household to treat his/her own warts with this stuff. Much less painful for you
I had something like this (similar thing - wart on finger, tried everything bar burying a hedgehog at a crossroads at midnight).
Believe me, freezing them is the ONLY way to go. However, I found the home freezing kits to be absolutely useless.
Didn’t seem to keep cold enough to do any serious work. Not sure if it’s the same stuff / temperature the professionals use, but it was a tenner down the drain.
I found the best thing for getting rid of these tenacious little buggers was… go to my local doctor’s. They froze it off with proper NO2 from a canister… almost a NO2 blow-torch. It effectively burns it off… It stings like hell, but once it scabs over, then heals, it’s gone for good - both the “crown” and the “root” (seems some home treatments don’t get the “root”). No more problems.
Hopefully there’s somewhere in your area that will do the same.
But get a professional to do it. The home remedies (for the real tenacious ones, and it sounds like yours is) don’t seem to work.
Personally, I prefer the laser to getting stuff frozen off. A laser is more accurate. The sensation is a bit more intense at the time of the treatment, but I’ve always had a bit of pain after a freezing treatment, but no pain after a laser treatment. In addition, since the laser is more accurate, it destroys less healthy tissue, and so my appearance afterwards isn’t so bad. All of this is just my experience, of course.
For home treatment, I take an insulin needle, and slip the bevelled edge under the wart nodules and gently cut the wart away. Since I do this when the warts are approximately the size of a grain of sand, this might not be practical for other people. I have exceptionally good close range eyesight, and I don’t care to have the warts grow large enough for a doc to treat them if I can help it.
