I have had a violent cough that produces clear sticky, stringy sputum (which dries a metallic silver in the sun) for 5 months. It started with a high fever, night sweats, and sinus infection while I was in Japan. They have ruled out SARS and all other infectious diseases (by a specialist). I have had multiple blood test (including TB tests), 2 sinus CTs, chest CT, 2 chest X-Rays, Upper GI, ultra sound, and a bonchoscopy, all of which were normal. I am being bounced between 3 specialists (ENT, Pulmonologist, and Infectious Diseas) and 2 primary care physicans...none of which know what is causing the cough. I have taken Phenegrgan w/ codeine, Guaifen (Duratuss),Singulair, Advair, Zithromax, Septra (had UTI at the time),Methylpred (MEDROL), Avelox, Hydrocodone, Prednisone, VI-Q-Tuss Syrup,Sulfamethoxazole, and Flonase - none of which have helped. I am now taking: Hydrocodone (which use to suppress the cough, but is no longer working...even at an increased dose), Astelin, Guaifenex G, Prednisone (again), and Protonix (even though GERD test are negative). I have a follow up appointment on Monday with the Pulmonologist and a allergy test with an Allergist (4th specialist in one week!), but am getting very discouraged and frustrated. I can no longer sleep because I cough ALL night (having to spit up the sitcky sputum; averaging 1 box of 250ct kleenex/week). I have NO sinus congestion, but am starting to run a fever again and am losing my voice. Cystic Fibrosis has been suggesed. Any suggestions? Please? ... with sugar on top??
