See someone: It sounds like you have a positive response to the test. This might mean that you have been exposed to tb in the past or possibly if you spent time overseas growing up that you had a vaccination that would cause a positive test. Or, worst case, you have to. You need to get this looked at as soon as you can before the reaction subsides

Cut my thumb deeply 3 weeks ago on a glass while washing up. It was big, but I treated it at home by rinsing and covering. The skin hasn't closed together, but new skin has formed under. Doesn't hurt now, but still very pink/ red/ small bump. Normal?
