Hope, I get that too. It is sort of funny but very strange. I had a single mastectomy so I have one natural breast & nipple and one implant reconstructed breast with no nipple. (I replied to this post because the itching problem happens to some of us whether we've had reconstruction or not).
If it has been many years since a person was infected with TB, his or her initial skin test may be negative, because of waning immunity. Subsequent tests may be positive, however, because the initial tuberculin placement stimulates the immune response to the test.
When you take a TB test, it takes about 48 hours to see if its positive or not. If a wheal (bump) forms and its itchy, DON'T scratch it, its really bad for the skin if you do.If its positive, you don't need to keep doing the TB test in the future, just the chest x-ray.
