Reoccurring Sinus Problem, Wax Build Up In Ears, Mucus, Nasal Congestion. No Relief With Medications?

Hi, my sinuses have been terrible for the past 3 years with major wax build up in my ears, lots of mucus , tons of nasal congestion . I have been to 4 doctors... all do the same thing, i.e. flush my ears out, put me on antobiotic, nasal spray and ear drops... Great.. feels good for about 3-4 months then it comes back...Now, its back....and the boogers that come out of my left nostril in the morning and evening look like something out of a sci-fi movie,.... I am also noticing that my poop is lighter in color and loose with mucus.... I m tired and not sure what to do next... any advise? thank you
