I have had wheezing in my chest for the last 4 days and I am not sure what it is. I had a doctor listen to my lungs and she said I probably had pneumonia because she could hear the wheezing. Due to Medical Insurance guidelines I had to go to my PCP a couple of hours to get a referral for a chest x-ray but when he listened to my lungs he said I sounded clear which I agree with. At that moment I was not wheezing. Thus, he said I was fine. Later that day the wheezing in my chest returned and has been on and off for the last couple of days. FYI, my daughter was in the hospital all last week with Pneumonia and Mono at the same time so I would not be surprised if I picked up her bug. I don't want to go on an Antibiotic unless I am sure what the noise in my chest is. Perhaps it is just mucus that keep accumulating and I just need to wait it out for it to clear up? I am 42 years old.
