Actually, post scabies itching can continue for more than a couple weeks in some people. It can even last a few months although there should be some improvement over that time. My friend was almost completely free of itching at about 3-4 weeks. I am still pretty itchy at 5weeks. We have both had thorough scrapings done and are free of scabies.Scabies once treated should only produce an autoimmune response to the debris of the dead mite and their feaces for about 2 weeks RN
I messed with my skin more than he did. I used sulfur and tea tree oil. That may explain why I am still itching or it may just be that I have more sensitive skin.
