If the phlegm is pale green and looks like it should be luminous, you have a chest infection and you need to go to the doctor to get it checked. Chest infections are mostly minor things but if not treated properly, can drain all your energy and turn into something nastier... that's how I got pleurisy, but it could just as easily have turned to something nastier.

If you are in the UK, I'm afraid to say that the tuberculosis case figures are shooting up and it's nothing to do with badgers.

I can sympathise with you... my sinuses have caused a 2 day migraine now, and I'm off to the doc tomorrow for the antibiotics I need for the chest infection I know I now have (smoky pubs do it for me....)

Good luck and we hope you're better soon.
