I am sooo sorry, really, no intention to offend; just saw the word scalpel and scrape and I know I used to do lots of harmful things to my skin in effort to get rid of it, but probably only succeeded in spreading it further. I am sure you are far wiser than I was. Please, accept my apologies, I know if you're dealing with the same thing I am, you certainly don't need to feel insulted. If you have not already, please visit the skinparasites.com message forum. It's the most helpful tool I've found with which to battle this infection thus far.
Best regards and good luck to you and your husband.
PS one of the worst things I have now is extremely wrinkled, thin skin esp. on the hands and feet. My feet have also developed hard callouses under which the skin feels numb or dead. When I scratch them I am able to remove tiny fibers, thinner than hair. Sometimes they are curly or wavy, othertimes straight. They appear clear or opaque. Does anyone else find these on their fingers and toes?
