Doctor insights on: Cough And Crackling Sound In Lungs

Share

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Barking cough after flu last week. Dr says lungs sound 'clean' and it's probably just from flu. Mild short of breath, mild wheezing. What to do?

Re-examination.: If this was just the flu, it would typically be resolving after one week, so the fact that you're still having symptoms has me curious, especially if those symptoms are pulmonary as you've described. I would have your doctor reconsider your diagnosis at this point. ...Read more

3 wk bronchitis cough wheezing. Back to doc yesterday listen to my lungs said sound wheezy but not infected. No x ray no meds is that even possible?

Asthmatic: Bronchitis is very common and some believe is due to allergc reaction to colonizing bacteria in the bronchial tubes The treatment is usually simultaneous administration of an antibiotic and anti asthmatic inhaler (s) X ray will be negative.

Worsening dry cough after viral illness. Short of breathe. Fast heart rate. Dr says lungs sound clear could still be pnemonia? Temp steady at 37.4

PFT work up: It is common to have a cough after most of the other symptoms of a viral illness have resolved. The shortness of breath though should not occur in association with the cough. This may represent bronchospasm or another cause. I would advise a pulmonary function test. If your lungs are clear and you are not febrile, pneumonia is less likely. ...Read more

My 7 year old son has had a chronic dry cough for about 2 1/2 months. I gave him singular did not work, he had chest xrays all good, lungs sound great, they did a "whooping cough test" negative. Cough meds do not work. No fever, acts like a healthy 7 year

My 7 year old son has had a chronic dry cough for about 2 1/2 months. I gave him singular did not work, he had chest xrays all good, lungs sound great, they did a "whooping cough test" negative. Cough meds do not work. No fever, acts like a healthy 7 year

The: The cause of a chronic cough can be a very tricky problem to figure out in kids or adults. Common causes include:

-asthma
-gastro-esophageal reflux
-allergies
-chronic sinusitis
-pertussis (whooping cough)
-habit cough
-pneumonia or other infectious cause such as tuberculosis

it looks like your son's doctor has been doing a good job thinking of these problems and trying to rule out each one with the tests and medication trials they have been suggesting. Most of these problems will cause coughing all night as well as during the day except for habit cough. I've attached a website with some information on habit cough which is very common in kids. I hope this helps. ...Read more

When I cough I taste metal. Has been going on for months off and on, typically taste it every day. I also get the sound of mucus congestion in chest?

Exam needed: I recommend a careful examination of the bronchial tree and lungs. A chest X-Ray may then be advised. Chronic bronchitis or atypical asthma (without wheezing) are possibilities. A sinus infection with postnasal drip is less likely. Treatment may include a course of antibiotics and an inhaler. ...Read more

The cough reflex is a protective mechanism that uses muscles in your throat and chest to expel mucous and saliva that may contain pathogens that would otherwise possibly be inhaled via aerosol or to expel pathogens infecting the throat and respiratory system. Cough benefits the host by reducing load and benefits the pathogen which may then spread via aerosol. ...Read more
