Husband recently treated for bronchitis and had a chest x-ray which showed black spots on lungs. Given z-pack for which only worked for a few days, back to dr for antibioics and steriods after developing pneumonia. Has had bronchitis and/or pneumonia annually in winter for over 10 years, otherwise healthy, non-smoker, 58 years. Took pneumonia shot several years ago. Going for additional x-rays, further diagnosis.
