This is not corns, but plantar warts, also known as boils. It is characterized by strip-shaped meat and black blood vessels, which are caused by human papillomavirus infection. I suggest you stop using corn frost, it will be contagious. If it is not handled well, it will spread to other parts, more and more. If it is always exciting to cut and scrape, it will grow bigger and bigger. Or go to the hospital for laser or cryotherapy. I found two photos for you. Please compare them:

This is corns, and the pain is caused by the inward proliferation of stratum corneum and the oppression of nerves. The white disc was cut from the dead skin, and the protrusion on it was corns. This thing will take root and sprout when it comes out of the corns.

This is plantar wart, the front is granular and the side is strip. It is a vegetation of the skin, not a dead skin hyperplasia like corns. Each one is rich in blood vessels and nerves, so it is particularly sensitive to extrusion and more harmful.
