I caught scabies from my grandchild who got it in school. I used the perimethen cream 5%, left it on for 8 hrs, showered it off then applied again and then showered off in about 10 hrs. That was on Wed & Thurs last week. Today on Sunday, I almost feel like I have it back. Does it still feel like you have it after you treated it. I didn t feel this until today, kinda of a sting, like when I got it earlier. I m worried I may have it back. I washed all my clothes and bedding in hot water and dried them in hot dryer and vac whole house and my mattress and couches. Is it normal to feel this?
