I've had this really stubborn cough for about 8 months now and it's sometimes so bad that I end up vomiting. I went to see a doctor and got tested for TB, but that came back negative. My X-ray did show some lower lobe subsegmental pulmonary consolidation. I was on medication for a while, and the cough got better, but as soon as I stopped, it came back. I saw another doctor who suggested it might be a gastric issue and told me to avoid spicy foods and fizzy drinks. But the cough is still here, and it's worse at night, sometimes leading to vomiting. I have to admit, Im still eating spicy foods occasionally, and I'm wondering if that's making it worse. What should I do next?
