Identifying Tiny Burrowing Biting Black Bugs?

Please help me. I have little bugs that are causing me to be miserable, with irritated bumps and sores. They are all over in hair, on arms, legs, and even in nose and mouth. Some of them when you dig them out will fly out of your skin. I know I'm ashamed to go out in public. I have had them for about 6 to 8 months. No one can help me. Also there are reddish ones.
