I would go to the ER last year, September, and complain of shortness of breath. They would tell me acute bronchitis, would take a chest x-ray and everything ok. My oxygen levels 98. I recently went through total hip replacement surgery and the anesthesia didn't do anything for me. In rehab, they had me in Albuterol and pulmocord. They would take chest x-ray, listen to my lungs, and determine I would be fine. The tech that performed my CT scan looked at some of the pictures and told me that there was nothing wrong he could see. My pulmonologist would listen to my lungs and determine there was no phlegm and sounded clear. I am having the breathing test done tomorrow. Wiill see
