Phlegm (Definition)

Phlegm is the thick, sticky mucus secreted by the surface of the respiratory tract during a cold or other respiratory infection. The respiratory tract includes the nose and sinuses, throat, voice box, bronchi, and lungs. Phlegm is mucus that may contain bacteria, viruses, respiratory surface cells, and inflammatory cells. Normal mucus is not phlegm, but a protective layer secreted ...Read more

Probably not....: With pneumonia, an infection of the lung parenchyma, there is usually discolored sputum that is coughed up consistently and there may even be some blood. Typically, there is a fever with pneumonia as well. If your symptoms persist, see your doctor since it is possible to have pneumonia with less severe symptoms but it is atypical. A chest x-ray can diagnose pneumonia if there is any doubt. ...Read more

Coughing up yellow phlegm. How do I know if it's from my lungs or throat? I do have a post nasal drip but that stuff generally looks lighter in color.

Coughing up yellow phlegm. How do I know if it's from my lungs or throat? I do have a post nasal drip but that stuff generally looks lighter in color.

Your sinuses: Most probably, as you would be much sicker if that phlegm is coming from your lungs, although it is still a possibility. Upper respiratory tract infection is more common, and your description of post nasal drip supports a sinus problem, you may want to see your doctor, as you may need an antibiotic, in the interim saline nasal washes would help, good luck ...Read more

I have all the symptoms of lung cancer: shortness of breath, cough with yellow phlegm and occasional red streaks, fingernail clubbing...but my Chest X-Ray and Noncontrast High-Res Chest CT were negative. Doctors are saying I'm fine, but I'm scared?

I have all the symptoms of lung cancer: shortness of breath, cough with yellow phlegm and occasional red streaks, fingernail clubbing...but my Chest X-Ray and Noncontrast High-Res Chest CT were negative. Doctors are saying I'm fine, but I'm scared?

Trust your physician: Or obtain a pulmonary medical consultation as a second opinion. Without symptoms such as weight loss. Anorexia, expectorating pure blood. Chronic spasmodic coughing, etc. This is not consistent with lung cancer, especially with a negative CT scan. I suggest behavioral counseling with a certified psychotherpist for CBT. ...Read more

Dry cough started end of march then that started producing yellow phlegm a week later. Suptum sample returned fine. No more phlegm, but still have irritating feeling of something stuck in chest + cough.

Not unusual: A lingering cough for 4-6 weeks after a chest infection is not unusual. The causes include a temporary asthma like condition due to constriction of the bronchial tubes. Patients may notice wheezing but sometimes cough is the only symptom. The cough will improve with inhaled medication to relieve the constriction......But you need to see your physician for a proper diagnosis, and quit smoking. ...Read more

What can it indicate coughing up yellow stringy phlegm, my chest is tight, feels as tho I've been punched in chest & back.

Bronchitis: This sounds like bronchitis. If you have been coughing a lot, then the pain in chest and back is due to this. The yellow just sign of infection. If it becomes chronic, you may need treatment, but most bronchitis will resolve without antibiotics within a few weeks. ...Read more

Pneumonia?: Suggest that you make sure that you do not have pneumonia. The bronchitis can present as you describe but you might want to see if you have had a chest xray. If not and you feel this bad I would ask to get one so that the pneumonia is ruled out. ...Read more

I am experiencing cough (quality: blood in phlegm, with phelgm or mucus) and arm pain. The following also describes me: Chest congestion. Green and yellow phlegm with blood. Was prescribed zpak. But afraid to take. Is there a substitute?

I am experiencing cough (quality: blood in phlegm, with phelgm or mucus) and arm pain. The following also describes me: Chest congestion. Green and yellow phlegm with blood. Was prescribed zpak. But afraid to take. Is there a substitute?

Take as prescribed: This sounds like a potentially serious infection, maybe even pneumonia. "Afraid to take" azithromycin (Zpak) is not rational; it is a very safe antibiotic with few side effects. Not treating your infection is MUCH riskier than any potential problem from the antibiotic. Take it as prescribed; if you remain concerned, discuss with the doctor who prescribed it. ...Read more

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
