Hello. I went to the doctor weeks ago with a few itchy bumps on my legs. I was told it was scabies and was given permetherin. I have now applied it three times, washed and cleaned everything in the house. Treated my partner (who displayed no signs of scabies) and my legs are now far far worse than when I started. I also have some on my arms and hands now. How could it get worse? Have I been misdiagnosed? Thank you
