What happens during a TB skin test?

No, it won't hurt. Not a big deal at all, not an elaborate test. All that happens is you get an injection just under the skin. They use a tiny thin needle, thinner than one they use for a regular shot. Then you go back in a couple of days so they can see if there was a reaction - that is the test. The person giving the test will explain more.
 
I've gotten a ton of them being a nurse and given about a billion skin tuberculin test. Basically it's a 0.1 ml intradermally (just under the first few layers of skin) injection of the tuberculin injectable solution. The injection is given on the forearm and, if properly placed, you should end up with a small raised redden area at the injection site. The skin test will be measures and read in 48-72 hours later.
Oh to answer the second question no it doesn't hurt.
Also don't scratch the injection site because it could swell and show a false positive.
