Two days back I had to go through a TB test on my arm. To be precise it was 40 hours ago. I have a pinkish reddish circle and the skin is a slight bump about the size of a pencil eraser. It looks like a fresh bee sting but smaller in size. It does not itch or hurts. The color has now started to disappear with time. Could I be tested positive for TB? Or am I just scared? What if I get a positive TB test? Please share your views.
