What Causes Pimples All Over The Body While Suffering From Anemia?

I am extremely anemic all my life and I have been getting tiny white pimples with the little hairs like trapped in that little pimple. There everywhere my legs butt, arms,back,chest, neck, and face. My hole body has thousands of these dark spots, black spots from head to toe. This has been happening for almost a year and half now. And now another summer is coming and I won t be able to go outside my house because I m so ashamed of my skin. My doctor gave me a prescription for an antibiotic cream for acne on my face. I used it it didn t work on face. What can I do, I am fare past the point of begging for help which I will do over and over just to get some help please.
