I am suffering from fever and chest pain

I am suffering from consistent light fever, cough, cold and severe headache from last few days. Sometimes I feel pain in the chest during breathing in. Chest pain is there from last one year. I went cardiologist several times but they found no issue. One of cousins had pulmonary tuberculosis and she died recently due to breathing problem. If I am infected from tb bacteria from last one year. What will be the condition of my lungs or other parts of my body. Yesterday I went to hospital so they perform sputum test. I am waiting for the test result. Please let me know about my health condition. If Dr found that I have a tb can this be treated and cured.? I am really afraid of this from yesterday
