17% salicylic acid( compoundW) caused scar, blister, culster of dead skin cells,etc? Can anyone help.

Hello.

I have some type of strange skin growth on my finger.

I had used a product called compoundW which is basically 17% salicylic acid and I may have had a bad reaction to it because I feel now there is almost like a ball of skin on the area it was used.

I have completely discontinued to use the product but I was wondering what is this mass of tissue which has developed and what solutions are there?

I am not sure if this perhaps scar tissue or just a collection of dead skin cells, etc....

Do you think that it could be freeze off with liquid nitrogen? ( I originally had a small wart on the area that was frozen off with liquid nitrogen ( healed perfectly) however the wart return. So I purchased the Compound W product.

Thanks for your help.
