Hi, Welcome to Healthcare magic,
is a contagious disease caused by a parasite that lives just under the skin. I hope you applied it from the neck down, left on overnight, & then washed it off & repeated the same in seven days. The cream that you are using is good, but just the cream is not adequate. You must also get rid of the contamination on clothes & bedsheet which have been used anytime during the three days before treatment. Make sure you wash your clothes etc with hot water, dry it under sun & iron your clothes before wearing it.
You must also make sure that everyone in the family/close personel contacts are also treated or else you could get reinfected from them.
There is an oral drug- Ivermectin
available. May be your dermatologist
will prescribe it if you vivit him again.
