Hi Dr. Rynne, I m seeing a pulmonologist tomorrow but I m hoping you can help relieve my anxiety until then. First, I have RA and have been on Humira since April. I had an indeterminate TB test and an unclean x-ray of my left lung in December so did a 4 month course of Rifampin. All of this may or may not have anything to do with anything but in April or May I started coughing. A few weeks ago, I went to my GP to find out why I was still coughing. He tried Singulair and Benzonatate. Neither have worked. I told him about the unclean x-ray and that I didn t understand what that was so he had me get another X-ray and a chest CT. Evidently the left lung is better but some abnormal things (maybe abscesses) have appeared on the right lung. I should mention that when I cough I sometimes bring up thick whitish mucus and my nose runs a little. I cough a lot during the day but very little at night in bed. Just wondering if you could give me a clue as to what s going on. Natalie
