bronchitis
"Took the 5 day Z-pack for this bronchitis I have had a month now. After the 1st day I felt great, but then downhill from there. 6 days after finishing it I wound up in the E.R., they gave the Z-pack again...much to my chagrin. I finished it 3 days ago and while I have more energy, my cough is still bad. I know the infection is still there, my white blood cell count is high at 18,000, but they also put me on Prednisone which causes high white  blood cell count. So they can't differentiate/determine cause of high white count, if infection or prednisone. Chest x-ray shows bronchitis. Friends who've had bronchitis are suggesting Bactrim, will discuss with my doctor."
