What Is Causing Sickness In The Stomach?

Hi I underwent to a chest xray and the result is non specific recticulonodular foci in the (L) upper lobe could be due to pneumonia or koch s infection. My illness has started as sore throat and developed into a cough for 4 days but I got that xray result. So I went to a pulmonologist and he gave me a diagnosis of ptb r/o pneumonia and prescribed an anti-tb meds that I have to take before I undergo to a sputum test? I had also a history of ptb last 2009 through xray only because the sputum tests were negative but the doctor said I have to take the 6 mos medication though the results is negative and I had also consulted the reaction of medicine I ve got during the period of medication, I had a yellow skin, vomitting, gastritis, stool become orange, problem with my eyes. Eventhough I confess all of my reaction to that anti tb drugs he still insists to complete the 6 mos medication. I had no choice but to take it. My question is do I have to believe on his diagnosis for this year over the results of an xray?
