Hi doctor. my brother was diagnosed with Bi-apical PTB, i was exposed to him before he took his antibiotics. after a week of being exposed to him, i had a flu symptoms ( sore throat, fever and colds) Does that mean that i was infected also? Today, I m experiencing mild chest pain, shortness of breath and back pain. But i don t have cough which is the major symptom of tb. I went to a pulmonogist and had a chest X-ray, the doctor said it was clear and no sign of mucus. but I m still bothered.
