Is it normal that i think i have fleas?
So I used to have lice about 5 years ago and it was resolved easily.. But now I've been very itchy in my head again but I just thought that it was normal head itches. But just about 3 months ago, I was scratching my head and a small really black bug came out? Call me disgusting, yeah I know so what.. I thought maybe I had lice again but I was confused because it was the size of lice but the color was black. I'm so confused and I think really the only answer is that I have fleas? I have one dog but I'm not with her often.. is it possible for humans to have fleas? Is it normal?
