What is the difference among clear phlegm, yellow phlegm, green phlegm, brown phlegm, and red phlegm?

The big difference between them is the color. Also, I wouldn't recommend taking antibiotics for anything. Let your body adjust and it will handle the phlegm on its own.

Give it a week. If it's not out of your system, then give kooky modern medicine a chance.

If you're feeling poorly and coughing up green or yellow sputum, particularly if you also feel short of breath, see your doctor, it's possible you may have a serious lung infection and would benefit from antibiotics.

The color of the phlegm can sometime distiguish between a viral illness and bacterial pneumonia. In general, clear is ok, yellow and green may be something to worry about, but red, brown and white are concerning. If you have a pneumonia you need an antibiotic.

OTC meds can treat the symptoms but will not get rid of the infection. I hope you feel better.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
