Hello I am a 42 yr old female, and for a job at daycare, I had to get a TB test done, and while there I received a tetanus shot. a day later I began to see these black (I'm African American if that makes a difference) spots showing up and they all over my torso, mostly under my right breast, on the side of my under arm, then on my legs, my stomach and I'm itching all over. I've tried using cortisone anti-itch cream to sooth the itching. I do have problems with eczema every once in a while but these spots are a mystery to me. help.
