Hi, I've Been Coughing For Almost 5 Months Now. When

hi,

I've been coughing for almost 5 months now. When i get a chance to visit a doctor, my first doctor diagnose me that i have an allergy even my x-ray show that i have pheumonitis middle right lobe. She gave me some medicines for my cough but the cough continues...last december 2015 i visit my doctor again to clarify what really my cough means for a long time, still she told me that i do an allergy. Since I am not conviced, I visited a specialist in Pulmonologist and diagnosed that i have tuberculosis. My question is how, in what stage of tuberculosis i am right now? i'm confused.
