Hi, Brenda,
It sounds like this may be a condition known as hyperkeratosis, or the growth of extra skin. This can be caused by inflammation or the exposure of the area to irritation of some kind repeatedly, or it can be a hereditary condition.
Here is the Aetna link which describes this and the various types:

You can get the Carmol cream online.
Google it for the best price...many places will ship to Canada.
Good luck and I hope this helps!
