question: i have the feeling that bugs are biting me all the time have been to dr ad they state that it is all in my head. although i can feel when i lands on me, which is a very small black thing. looks like a hair after you get your hair cut. they are on my face ears private areas arms. if you can tweeze the fine black like thing out fast it will not grow. they then turn white, after awhile they are brown. they are in my mouth also and have rotted almost all my teeth since june of last year. i have been to dr s 9 times.
