Pain reliever
I was given some by podiatrist for my painfulcallus. I ordered more, as this was going to be a long haul. Also used Dr.Scholl's callus remover, which made it worse. But over time, it healed, so that I didn't need the callus pad. But now I have a callus on other foot, which is not as bad, but necessary to apply callus pad. You don't need to use a new pad often, even after a shower, when I alternate with adry used one. When loses stickiness, use paper tape on sides to keep in place.
