Hi. I m having itchy crawling things in my head. When I itch it, nothing comes out. I picked up a hairband on the ground in target parking lot on Saturday and used it for my hair for work, forgot to take it out. Could it be caused by it? Also feeling crawling things on me at night, and find red bumps all over, also black tiny dots burrowed in my skin, and white things small dots crawling on my face & body. What is it?
