I used the cream (2 applications 7 days apart) skin dried out and most of it cleared up but I'm still feeling my scalp (which I was told not to use the cream on) is still itching all day/night and my arm & neck are raw/red/bumpy. Still feel like things are crawling on me & have both Itching/burning sensation on areas that doesn't go away. Neck has a watery liquid seeping at times when scratched. Is this an adverse reaction or do I still have scabies???
