My grandmother has scabies and I put the premerthrin cream all over her body with gloves. Now its been a day and as soon as I was trying to go to sleep, I feel crawling and a few itches on my body. Especially on legs, groin. I found a red bump on my hand and leg.

What can I do now to get rid of these for good?? Do I have it? Is there any way to know for sure? and can I sleep in the same bed now?
