Well I would definately listen to the ex-RT and your Dr. Just keep an eye on it. If it is something that continues to bother you I would go to the Dr. No one knows your body better than you do. I think that as humans we forget the fact that our own bodies will tell us when there is a problem with it.
Doc says it's excess mucus, post nasal drip, caused by allergies but, I don't know. I don't really have too much trouble with allergies and can usually breath through my nose fine at night. I occasionally use a neti pot. I found, while researching some GERD information for a friend, information about another kind of acid reflux called LPR or silent reflux. I have so many of the symptoms. Chronic cough, trouble swallowing, asthma like symptoms, wheezing, post nasal drip.
Just thought people on the forum might like to know about LPR. I don't remember reading about it during the discussions on GERD.
You know it's funny, just after my last post about this in April I started taking Tums before I went to bed and, ta da, cough went away. Thought I'd cured myself. Well here I am again. About 2 weeks after the start of school my 6yr old brought a cold home, I got it too. Wasn't too bad as far as colds go, pretty mild. But, I've been coughing again ever since and have the crackling too. I still take Tums before bed.
My daughter was having problems last year too and we've had her to a lung specialist several times. She coughed for months! No crackling though. We were going to start her on asthma medicine but decided to see how she would be when we went on vacation to California at the beginning of summer. Well guess what, we went on vacation and her coughing went away! Sigh..now she's coughing again too. We just talked to the GP doctor this week because she got the flu. When I told him that she has been coughing again for some weeks now he said, after looking at the lung doc's notes, she is diagnosed with asthma. Mother's intuition...I just don't think it's asthma. Why are we both coughing? Maybe it's mold in the house or something. He said no, you probably have asthma too.
