sounds as a good opportunity to stop smoking. You could experience even more mucus for some days or weeks after that, though, since lungs usually clear up the mucus after stopping smoking.

When did you quit smoking? I recommend you to find a doctor who will listen you. A lung doctor.

You can check this personal medical history questionnaire and write down all your symptoms, when you started and stopped to smoke, have you taken any drugs, is there any asthma in your family and so on. This info can help the doctor a lot.

With all that mucus and inability to sleep, there’s obviously something wrong. If you quit smoking only recently (weeks), the mucus may be from lungs clearing up. But there can be bronchitis, bronchiectasis, tuberculosis… Microbiological test of the mucus (sputum) and blood test can show, if there is any infection, and you can get antibiotics if necessary. At least, the doctor can give you something to clear the airways. Do not try antibiotics without prescription, since this may prevent your doctor to give you correct diagnosis.

I strongly recommend you to visit an infectologist. A lung infection is possible.

For the past few weeks i have been suffering on and off from cold symptoms which never amount to a full blown cold. I suffered from terrible back pain under my shoulder blades and pains in my solar plexus for the first half of this week which caused breathlessness and general discomfort. I am constantly tired, have headaches (which is very unusal for me) and am coughing up green/brown phlegm.

I am a social smoker but have recently been on holiday where i smoked more than usual.

Any ideas what this may be?

colds and mucus can be symptoms of gastrointestinal infection. I recommend you to visit your doctor, who can perform appropriate tests.

sore tonsils and uvula can be a symptom of viral or bacterial (this would go with fever) throat infection. If you decided to cut down cigarettes, now is a great opportunity to quit it completely. Mucus of various colors can actually appear in great amounts after quitting smoking – this is a sign that lungs (bronchi) clear up. This may last for several days or even weeks. Mucus coming down the throat could be from sinusitis (facial pains, triggered by tapping the cheeck bones or front)or a simple cold.

Try to stop smoking completelly. Mucus may even increase. If you get fever, or nose doesn’t clear in some days, visit a doctor to get diagnosis and antibiotics, if necessary.
