My friend has been sick for the past year, coughing, chest pains, the typical cold and flue symptoms, very very tired, and totally out of it, at first I thought she may have Hep, but being in the dental field, we were immunized for it,she finally went to the doctors 2 months ago, and they took a chest x-ray, she was told she had walking pnemonia and she one course of one brand of antibiotic, and a different kind, her symptoms were improved but they returned, she went back for another chest x-ray and the doctor told her she has scars from TB showing up on her lungs, and he wants her to see the specialist. I asked her if she had the TB skin test yet, she said doctor said that was not needed, I told her did the doctor say she was contagious because she has been coughing and having nite sweats and not being able to breath and a constant flu symptoms and she said no she doesn't have TB. Is this true, you don't need a TB skin test and when do you become contagious?
Thank you
