Can someone tell me if they ever experience goose bumps for no reason at all. They come on all of a sudden. Not your normal goose bumps all over, no, goose bumps that come in patches. I'll feel a small spot on my arm getting them and when I look, I can literally see them come up. I can see the hairs stand on end but in one small little patch. OR I'll feel them on one side of my face or on one thigh. I'll not only feel them I can see them!! What is up with that? Can someone please tell me if this is something I should be concerned about? Pleeeease let me know.
