Cough, cough, cough

I have been struck with a nasty cough these past 3 weeks. I don't think I've ever experienced this long and stubborn of a cough before, ever, in my lifetime.  It first started with a sore throat end of January and then the coughing began and it never stopped.  Of course I thought the coughing would eventually go away, but 3 weeks later, I am still coughing.  Worst is that sometimes I will have these cough spells that can go on for a good 5 minutes.  My throat gets super itchy and then I cough and cough until tears roll down my cheeks and my face turns flushed red.  It's really embarrassing (not to mention annoying) when I have these uncontrollable cough spells.  I finally went to the doctor's this past Tuesday.  I was afraid that I might have bronchitis, but thank goodness I didn't.  My lungs are clear.  The doctor thinks I have a post-nasal drip, caused by sinusitis.  Basically my sinuses are congested and the mucus that accumulate in that area falls into throat, causing me to cough.  I got prescribed Codeine and OTC Claritin.  Took the meds for 2 days now, and there seems to be a sight improvement to the cough. I just want to be done with this cough!!  It's really annoying.  Not a great start to the year, health-wise....

Update (2/19/2011)
I can't believe that due to my excessive coughing, I've pulled a muscle in my left rib area.  It is painful whenever I deep breathe and extremely painful when I cough!  It even hurts when I put on a jacket or lift up Sarah.  This is not good.  This is not the progress I was looking forward to.
