Cough and Nasal Congestion
"I have experienced fluid in my ears for almost two years.  Consulted with two ear and nose specialists and with an allergist.  Tried three types of nose sprays and other natural options, like additional vitamin C , pollen defense and the  neti pot.  Nothing worked until just recently I developed a severe cold and took Mucinex D.  To my amazement and happiness the fluid drained from my ears.  Clear ears!  Problem - one cannot take Mucinex on a permanent basis."
