Ppd Test

Hello Everyone I am new to this website. I had to take a two step TB test. I had one in September and it was slightly red. I had One The first week Of January and was just a little red. Then I got another one 14 days later and to me looks really red with a slight bump. My doctor said it was negative. I am freaking out because it is so itchy and it got inflammed i keep picking on it! My dad comes from another country and he has been here in the U.S since the 70's. In his country there is presence of TB. Maybe he has it latent?//And I got it..I am just freaking out. I got it done on Thursday. Should I tell my doctor to give me another one. I don't see her until three weeks. Should I call her and tell her is irrriated and itchy. For all the people with experience in the health field. Should I worry? Or should I just Request a chest x-ray??
