Doc, I have findings in my lungs last Nov 18, 2013. I was given already an antibiotic for 5 days and I made an xray again on Nov 28, 2013 but the findings was still there. I was given another type of antibiotic which is Zenith for 5 days and I undergone xray again on Dec 14, 2013 but the findings has never changed. I was given another medicine and I made another xray this January 7, 2014 but still no changes at all. The findings is in my upper right lungs. What is my illness Doc? Am I positive for TB? I made a sputum test last December 20, 2013 but the result is negative. Please help me. Thanks
