For the last 4-5 years, I have been suffering from mucus getting thicker and harder to cough up. This had been thought to be chronic bronchitis.
A couple of weeks ago, during the intesive morning cough, I experienced small proportion of vivid red blood in my sputum, this happened about 3-4 times, during the past 2 months. My lung X-ray was normal. I copy my lung function test results below:
FVC: 92%, FEV1: 102%, FEV1/FVC: 112%, FEF25-75: 107%
TLC: 109%, TGV: 131%, RV: 130%, RV/TLC: 114%
Raw: 68%, sGaw: 145%
This seems to be excellent ventillation but with some clear signs of lung hyperinflation. Do you think that I may have bronchiestasis or ephysemia?
According to that I also have chronic sinusitis with thick nasal dripback and GERD, would you think it would be wise to take a sweat chloride test to rule out CF? I also have a loose, floating stool.
I am a 28 male, and never had pneunomonia or so. But the blood appearing, and the the thick mucus paired with the high residual volume frightens me a bit.
I wake up sometimes experiencing yellowish acid reflux in my mouth. Could all of these be a chronich bronchitis amplified by GERD, or a more severe condition like CF, ephysemia or so? I have taken a C-reactive protein test, which showed no acute inflammation, my blood O2 saturation was 97%. Serum Sodium level was normal.
From here, what kind of additional tests would you recommend, please?
