What cause of cough mucus blood from mouth?

Cold. There are sources of blood, like the stomach, the lungs and the nose and posterior pharynx. In time of cold or upper respiratory infection, there is mucous which is thicker than the plasma. This draws the fluid from the blood vessels in the nose and the pharynx which are to the surface and they can pop and hence you cough up blood. If possible other causes, please go see your doctor.

Smoker with anxiety symptoms. Cough mucus short of breath. Heard quitting causes shortness of breath. I ALREADY can't breathe. Nervous to try.

That pattern alone can lower BP (for awhile) and makes you feel really good. When smokers quit, they lose this advantage. Some of the distress is due to this. You can win by continuing to do the breath pattern w/out the cigarette! 'Smoke' w/out cigarettes! Read more...
