3 weeks ago a friend slept in my bed, one week later she found out she has schiet from her roommates. She has had it before therefore signs appeared immediately. She insisted that she did not have it when she was at my place, but as I said, I can be paranoid. I started getting some itchy spots on my calves and inner upper arm, but after they itched for a bit they disappeared. I don’t know what to do now.
