coughing up specks of blood in mucus

The blood could be from the back of the nose or the throat from small surface blood vessels that pop from the drying effect of the mucous but since I can't examine you, it is best to see your health practitioner to examine you and give you more peace of mind. More exams may be needed which can't be done here.

Viral upper respiratory infections usually start in the throat, spread to the nose and in some cases down to the windpipe and bronchial tubes. If symptoms last longer than 10 days or with fever, shaking chills, sweats or worsening cough, antibiotics and a check up for pneumonia are advisable. Until then a mild cough syrup and gargling with warm salt water is soothing. Tylenol for mild fever helps.

There are many possibly causes including but not limited to tuberculosis, pneumonia, or tumor. Also other lung disease. Thus this symptom needs immediate evaluation b/c the possible diagnosis could be dangerous. Please make appoint with your doctor

This can be from post nasal drip. Do you have any nasal congestion? headaches or sinus pain? Treating them will alleviate your mucus. Try an over the counter saline nasal spray and see if it helps

An ENT Dr can do an exam including looking down your throat with a small fiberoptic camera and help identify the problem and its treatment rapidly.

were you diagnosed with it and treated appropriately? if so, the cough can linger for a few weeks, some months after the infection is treated. If you did not get it treated, go now, this is very contageous

lasting a month would demand full evaluation by your doc

See a doctor for evaluation. Do not delay

Alcoholics can have bleeding from the esophagus due to abnormal veins, called esophageal varices. These abnormal veins can then bleed, sometimes catastrophically leading to death. When they bleed, it can look like the person is coughing the blood even though it is originating in the GI tract or, they can actually aspirate some of this blood and then cough it up.
