I applied 60 grams permethrin cream a week ago, seemed to temporarily make the scabies movement and itch subside briefly. But it came back. Applied straight kerosene to groin area 2 days ago. fluttering subsided substantially in groin, but lots of itch and flutter elsewhere. Applied 1 cup of kerosene over whole body last night, got good sleep, bathed in morning. Itch is back strong in arms and chest today, so I think some are still alive. Any suggestions?
