Enquiry About Cause Of Constant Phlem

Dear doctor,
           I am having phlem for nearly 1 year. I have taken multiple antibiotic and some anti-allergic prescription from clinic and hospital's specialist doctor. I did try on the nasal spray for 2-3 months but none of it seemed to cure the constant pflem that seem filling up my throat from time to time.
I had done a chest X-ray and also a blood test to check the white blood count and everything is normal.
           Let me describe my symptom in more details.Each morning after I woke up, I will take a warm shower before going to work and usually after or during shower, I will have some running nose but after I sneeze it out, my nose will be clear. Then during the whole day I will have phflem seemed stucking at my throat. ( I don't know whether it comes from the nose but I don't feel my nose is wet or stucked). The pflem color range from transparent,yellowish and greenish. Sometimes, there is even little blood within the greenish phflem. I don't cough so sometimes I need to suck out the phlem from the throat but sometimes the phflem just emerge itself. When I play sports, usually there will be lot of transparent phlem that I need to dispose off. Although I have been drinking water a lot, I felt dryness and discomfort in my throat and my lips look very reddish. Sometimes it look like I am going to have sore throat but since I have this constant phlem sysmptom, I didn't catch any cold or influenza(which usually start throat, fever, running nose and cough).I don't have fever nor lose any weight.
             Thank you very much for any valuable opinion.

Postnasal drip is drainage from the nose and sinuses dripping down the back of the throat.  It is possible that postnasal drip is due to a cold.  It is also possible that postnasal drip has nothing to do with a cold.  This can cause irritation of the throat that you feel as a discomfort in your throat.  The blood could be from the irritation.  A nasal wash helps remove mucus from the nose and sinuses.  This can temporarily reduce the postnasal drip and lessen your throat discomfort.  A prescription nasal steroid spray decreases nasal swelling and mucus production.  This may prevent the postnasal drip and your throat discomfort.  To get the most out of a nasal steroid spray use it after doing a nasal wash.  A nasal steroid spray does not provide immediate relief of symptoms.  It may require several weeks of routine use to become effective.  Please read our Nasal Wash MedFact at http://www.nationaljewish.org/medfacts/nasal.html for more information about this technique.  Share this information with your doctor to see if you would benefit from this daily treatment.  Green mucus generally indicates an infection that is often treated with antibiotics.  The water that you are drinking will help by thinning the phlegm so that it moves easier.
