In winter of 2007 I got body lice from my roommate I lived with earlier that summer (it didn't show until winter), I got treated with Benzyl Benzoate.
I thought I got ride of it up until winter of 2010 when I started itching and notice the bugs glued to my skin over chest and belly, I treated it with Lindane once and it went away.
Almost two weeks ago it came back, I found a bug on my chest, so I immediately used Lindane last week, yesterday I found a bug on my hips and I've been itching today!

Why isn't it going away? It has been 5 years! I first thought it was crabs but figured its scabies
What should I do? Please help
